. The influential effects of jointed angles on wave propagation, energy transmission and dissipation were studied when the stress waves went through the jointed plane. An empirical model for energy dissipation ratio to the jointed angles was formulated. The results show that under the condition of similar incident energy, when the jointed angle increases, the reflection energy ratio increases......

The results show that the flow stress decreases with the increase of deformation temperature at a constant... during hot compression deformation can be represented by a Zener-Hollomon parameter in the hyperbolic sine form. The efficiency of power dissipation is much higher at high temperature and low strain......
dissipation and yield mechanism under the inelastic seismic behaviors. The base shear and lateral force distribution were derived from modified energy balance equation and the code for seismic design of buildings. Moreover, the pre-selected target drift and the reduced energy dissipation coefficient η were also important to the proposed method, and all the elements were obtained by plastic design method......
