Speech Title: The strain rate intensity factor in plasticity and its applications

Abstract: Narrow fine grain layers of material are often generated in the vicinity of frictional interfaces in manufacturing processes as a result of severe shear deformation. Such layers affect the performance of structures and machine parts under service conditions. Therefore, it is of importance to develop a method to connect parameters of manufacturing processes and parameters that characterize properties of fine grain layers generated by these processes.
The objective of the present paper is to develop a general approach to relate the strain rate intensity factor introduced in and parameters that characterize the microstructure and thickness of fine grain layers. This approach is used in conjunction with axisymmetric direct extrusion of an AZ31 alloy. The thickness of the fine grain layer is determined experimentally. Also determined is the distribution of average grain size and hardness near the friction surface. The strain rate intensity factor is found using an available semi-analytical solution.

Speech Title: Microscopic studies of bioconjugates of nanocarbons

Abstract: Hybridization of biomolecules and nanocarbons is effective to enhance specific properties of the nanomaterials. Wrapping of carbon nanotubes (CNTs) is an example of the hybridization procedures. By wrapping CNTs with biomolecules such as DNA, water soluble isolated CNT hybrids can be fabricated. Solubilization is important especially for biological applications because many of biological applications are realized in aqueous solutions. Isolated CNTs reveal extraordinary optical properties, in particular, near-infrared area. Therefore, hybridization with biomolecules is effective to improve functions of CNT nanodevices.
In this talk, I introduce overview of nanobiosensing using bioconjucates of CNTs. Near-infrared spectra of the conjugates dramatically fluctuated due to CNT conditions and atmosphere around the conjugates. Several research groups have focused on developing new nanobiosensing techniques using the specific optical responses. It has been reported that the spectra were changed when an aliquot of coffee, caffeine, ascorbic acids, glucose, or dopamine was added to the conjugate solutions. In our case, we evaluated catechin that is one of the major components of Japanese teas. Furthermore, disappearance of the catechin effects could be detected using the bioconjugates.

Speech Title: Mechanics Modeling of Metal Additive Manufacturing

Abstract: Recognized as a milestone technology, additive manufacturing (AM) has promised unparalleled part complexity and small-batch cost effectiveness. However the control of AM throughput and build quality has been challenged by the deficiency in the fundamental understanding of materials mechanics to support systematic prediction, monitoring, and optimization. a fair amount of experimental observations and numerical finite element modeling (FEM) studies have been pursued and documented, but they unfortunately suffer from the need of trial-and-errors and the lack of knowledge extendibility. Aiming at a scientific scope and engineering applicability far beyond experimentation and FEM, physics-based analytical modeling flanked by computational mechanics of materials is developed at Georgia Tech and presented herein to quantify the thermodynamics, heat-transfer, and materials thermos-physical behaviors in powder bed and powder feed metal AM. Closed-form solutions have been established for temperature distributions. Subsequently the corresponding thermal stresses, residual stresses, microstructure, build distortion, and mechanical properties are expressed as explicit and algebraic functions of process parameters and powder properties, factoring in the effects of scan strategy, and powder packing. Bounded-medium solutions have been established by folding boundary thermal balance conditions into the traditional semi-infinite medium solutions to compute material responses near build edges without iterations. Extensive experimental validations are also presented. The solutions deliver more penetrating physics of the metal AM process, showing much higher accuracy, and costing less than 1% time of commercial FEM’s, thus promising effective prediction and optimization for first-and-every-print-correct AM.

Speech Title: Analysis of Viscoelastic Behaviour of PLA/PMMA/PBAT Blends with Compatibility and Composition for Eco-environmental Engineering Fields

Abstract: Firstly, viscoelastic behaviour of PLA (Poly lactic acid) was analysed as an eco-environmental geosynthetics. PLA has a slow crystallization rate and low thermal stability, which causes a sharp decrease in molecular weight at high temperature during processing, resulting in a change in physical properties of the final product and a low impact strength with a rigid chain structure. In order to improve low impact strength, heat resistance and fluidity of PLA, methods such as copolymerization, crosslinking, and polymer blend are also applied. Among them, blending with a flexible polymer is adopted as a most economical and efficient method. In addition, various polymer resins such as ploycaprolactone (PCL) and poly- (buthylene succinate) are used for blending with PLA, but PBAT (poly butylene adipate-co-terphthalate) has high impact strength and elongation. In this study, the viscoelastic behaviour and tensile properties of PLA blends and PLA/PMMA/PBAT blends were measured, and an image analysis was performed, to examine the compatibility of PLA, PBAT, and PMMA. PLA/PMMA blends were found to exhibit a high level of compatibility for all compositions. The thermal stability, modulus, and tensile strength of these blends increased with PMMA content. Also, the glass transition temperature and tensile strength of PLA/PMMA blends are varied by blending composition between PLA and PMMA. On the other hand, ternary blends of PLA, PMMA, and PBAT exhibited a low modulus than PLA/PMMA blends; their compatibility improved with PMMA content because of PMMA acting as a compatibilizer for PLA/PBAT blends. From this, it is expected that the development of incompatibility and mechanical property may be obtained by blending of two different biodegradable polymers which are not compatible each other.
Secondly, Eco-friendly environmental concept in PLA geosynthetics application was reviewed. Green revolution is rapidly increasing in every construction sites e.g., green structure, green installation, green industry etc. especially on the eco-environmental point of view. Biodegradable geosynthetics as a green material could be made from eco-environmental polymeric resins and they must maintain their needed performance during service period in the real field application. The basic technology trend and concept of biodegradable geosynthetics is reflected to eco-environmental growth in civil engineering fields. The important concept of biodegradable geosynthetics is focused on their degradable behaviors of used resins and needed performance for engineering qualification with evaluated technical data. Therefore, it is very important to select what kind of raw resin, additives and plasticizer to control the biodegradability. In this study, to consider this, environmental availability of biodegradable geosynthetics by PLA (poly lactic acid) was introduced and reviewed to be related to the quantitative analysis of degradability as long as biodegradable geosynthetics are installed in soil structure. And technical availability of biodegradable geosynthetics was introduced as green geosynthetics and reviewed to be related to analysis of degradability by conceptual consideration. The important concept of biodegradable geosynthetics is focused on their degradable behaviors of used resins and needed performance for engineering qualification with technical data of designing. Through the overall review of degradability of biodegradable geosynthetics, it is seen that biodegradable mechanism could be controlled theoretically and more restricted design technology must be adopted in the quality control and assurance of manufacturing procedure in the installation field. Finally, to evaluate the degradable performance of biodegradable geosynthetics, new test concept and the needed evaluation items should be selected by considering influence parameters on the long-term performance under real field installation conditions. PLA based geosynthetics will be used in the special and alternative application fields if biodegradable mechanism could be controlled.
