...Chensong Dong The coefficients of thermal expansion (CTEs) of fiber reinforced composites play an important role in the design and analysis of composite structures. Since the thermal expansion coefficients of polymer matrix materials are typically much higher than those of fibers, and the fiber...

...Xin Lei; Cliff J. Lissenden Discontinuously reinforced aluminum (DRA) is currently used where design considerations include specific stiffness, tailorable coefficient of thermal expansion, or wear resistance. Plastic deformation plays a role in failures due to low cycle fatigue or simple ductile...

... of coefficient of thermal expansion of the reinforced magnesium shows dimensionally more stable magnesium as compared to monolithic magnesium. The hardness 0.2% YS and UTS were found to improve significantly after addition of nanosized SiC and nanosized hybrid Si C + Al 2 O 3 particles to the magnesium, However...

...Russell J. McDonald; Peter Kurath Thermal cycling has been experimentally demonstrated to diminish the performance of many reinforced materials. The coefficient of thermal expansion mismatch is the driving force for the development of high self-equilibrating stresses and strains in the vicinity...

... of the interatomic potential and temperature. We have studied the temperature dependence of specific heat and coefficient of thermal expansion of graphene and diamond, and have found good agreements with the experimental data without any parameter fitting. We have also studied the temperature dependence of Young’s...

...H. Jiang; B. Liu; Y. Huang; K. C. Hwang We have developed an analytical method to determine the coefficient of thermal expansion (CTE) for single wall carbon nanotubes (CNTs). We have found that all CTEs are negative at low and room temperature and become positive at high temperature. As the CNT...

The numerical simulation includes elastic-plastic behavior of the confinement, thermal expansion effects, the mechanical and thermal response of the explosive, and a discrete...

...Martin Y. M. Chiang; Chwan K. Chiang; Wen-li Wu A technique for determining the in-plane modulus and the coefficient of thermal expansion (CTE) of supported thin films has been developed. The modulus and CTE are calculated by solving two coupled equations that relate the curvature of film samples...
