Material and Structure Dynamics的意思|示意

On the basis stated above, a numerical method of plastic dynamics and material failure judgment are used to analyze the causes of joint failure from the aspects of structure and internal pressure.

据此，从结构和内压角度，应用塑性动力学的数值方法和材料的破坏判据分析了引起接头脱落失效的几种因素。

However, the elastic modulus and loss factor of viscoelastic material usually change with frequency, which will cause difficulties in the calculation of structure dynamics.

但是，由于粘弹性材料的弹性模量和损耗因子往往随频率变化，对设计计算造成了一定的困难。
