实心球体在热冲击下的动应力和某些现象
DYNAMIC STRESSES AND DYNAMIC STRESS-FOCUSING EFFECT IN A SOLID SPHERE UNDER THERMAL SHOCK
【摘要】 本文提出一种简便的解析方法求解实心球体在热冲击载荷作用下的动应力响应。从热动应力的解析表达式和计算结果可以发现圆心处的动应力具有动应力集中现象,并且随着应力波在球体外边界的不断反射而产生周期性振荡。
【Abstract】 This paper presents a simple analytical method solving the dynamic stress response in a solid sphere under thermal shock. From analytical expressions and calculating results we can observe that there is concentration of the dynamic stress at the center of a solid sphere and periodical oscillation due to the continual reflection of stress wave at the external boundary of the solid sphere.
