Sintering driving force at the initial stage of pulse electric current sintering under thermoelastic
The sintering driving force of nonconductive Al2O3 powders at the initial stage of pulse electric current sintering is investigated by analyzing the thermoelastic diffusion coupling transmission under
Based on hybrid FEM/peridynamics implementation,the SLA(Sequential Linear Analysis)algorithm is applied to simulate static crack propagation in rock-like materials.
线式分离结构作为弹箭体结构的主要承载结构连接相邻部段，又承担分离功能。由于线性分离结构要满足安装承载要求，故而截面形状多变。在飞行过程中导致线式分离结构处于复杂的热流条件下，对线性分结构防热设计带来困难。
