应力传播 meaning in English

stress propagation

As the time microscale factor in fast transient high - strength heating or cooling can not been ignored , heat relaxation time is introduced . based on hyperbolic heat conduction equation and kinetic equation added inertia , theoretical analysis and study of stress diffusion and transformation in heat impact process were developed
考虑到快速高强度加热或冷却带来的时间微尺度因素，引进热松弛时间，以双曲线型热传导方程和考虑惯性力的运动方程为基础，对热冲击过程的应力传播与变化规律进行了理论上的分析和研究。
