A new result enables direct calculation of thermoelastic damping in vibrating elastic solids. The mechanism for energy loss is thermal diffusion caused by inhomogeneous deformation, flexure in thin plates. The general result is combined with the Kirchhoff assumption to obtain a new equation for the flexural vibration of thin plates incorporating thermoelastic loss as a damping term. The thermal...

Microelectronics failure during operation is commonly attributed to ineffective heat management within the system. Hence, reliability of such devices becomes a challenge area. The use of lead-free solders as thermal interface materials to improve the heat conduction between a chip level device and a heat sink is becoming popular due to their promising thermal and mechanical material properties....

Equal channel angular rolling (ECAR) process is one of the severe plastic deformation (SPD) methods that have been used to make ultra-fine grain (UFG) materials with improving the mechanical properties of samples. After performing the process at several paths, a large strain is applied to the material that can cause decreasing the grain size and improving the mechanical and physical properties ...

In this paper, radiation pressure induced deformation of a series of thin aluminum reflectors is analyzed theoretically and experimentally. Theory of quantummechanics andmaterialmechanics are applied in 2D simulations and exhibits good coordinationwith experiment results. The original laser source used in the experiment is Gauss-distributed and has been shaped and expanded, resulting in theflat...
