Opis:: The frequency for the first two modes of vibration of a nonhomogeneous tapered rectangular plate is calculated under a bi linear (i.e., linear along both the axes) temperature field. For consideration of the nonhomogeneous material, the author assumed circular variation in Poisson’s ratio. Tapering in the plate is assumed to be linear in one direction. The results are calculated for different values of plate parameters and presented with the help of graphs. Comparison of the results is also given, to support the results of the present study.

Opis:: Young’s modulus, yield stress and Poisson’s ratio are studied for different size and tem- perature. The temperature dependence of simulated Young’s modulus is quite similar to experimental results. Transverse sound velocity is estimated from the simulated elastic con- stants at each temperature. The dislocation speed reaches up to 75% of the transverse sound velocity. The dislocation speed decreases with increasing temperature linearly. The tempera- ture dependence of macroscopic deformation behavior and the possibility of the existence of supersonic dislocations are discussed. The transverse sound velocity and rigidity G is calcu- lated from Young’s modulus, Poisson’s ratio and density ρ which changes with temperature.
