Modeling microstructural effects of deformation resistance and thermal conductivity
This is a study of the microstructural influences on thermo-mechanical behavior of selected metals and ceramics using computer simulation, with original contributions in both theoretical and applied aspects. There are three major thrusts. First, by constructing a many-body empirical potential for …

Study of Nozzle Design and Development of Reinforcing Mesh Approach for 3D Construction Printing
… to printed accuracy, interlayer bonding, and deformation resistance. Also, the key barriers faced in optimising nozzle-related parameters could be categorised into four aspects, namely: (i) technology, (ii) market, (iii) economic management, and (iv) social environment. Further, nine nozzles …

Mechanisms of Metal Penetration in Solid Electrolytes
… density scales inversely with the mechanical deformation resistance of the electrodeposited metal. We then present two novel electrode architectures in which a liquid phase enables higher critical current densities via interfacial stress relief and current homogenization. First, biphasic …

Performance of recycled polymeric fiber as reinforcement in bituminous mixture for road maintenance works
… mixture has improved by 120% whereas for rutting resistance of RPET FC mixture has improved by 32% compared to control mixture. A field test was also conducted in this research. After 500 vehicular passes at service temperature (45oC), deformation resistance in the reinforced test pit has improved …

Passive Site Remediation for Mitigation of Liquefaction Risk
… the influence of colloidal silica grout on the deformation properties. Distinctly different deformation properties were observed between grouted and ungrouted samples. Untreated samples developed very little axial strain after only a few cycles and prior to the onset of liquefaction. Once …
