摘要
热应力是一种常见的普遍现象,是辐射加固技术和激光武器效应必遇到的一个问题。因此,对其剖析,具有较大的实用价值。本文叙述分为五部分:简化假设,基本公式与求解方法,激光照射产生的温度分布,热应力的求解和几点结论。
The thermal stress is a usual and general phenomenon, and it is a problem which encounters in the radiation hardening technology and laser weapons effect, so then, the analysis of the thermal stress posseses very important practical value. On the analyzing for the unsteady thermal stress, many scholers always adopted the Laplece transformation. In this paper, on the basis of the property of the linear equation, we applied with direct way of superposition principle. In the processing of all the calulation, we felt deeply that the former is complex and the later is simple, so Laplace transformation is not a kind of optimum method. The two kinds of the results express different forms, in this paper we gave the transform formula of the both. Looking for the Love displacement function is not a unified standard method until now, in this paper we adviced on it a general and reference way. Becauce of the complication of the question, in the preface of this paper, we gave some simple hypothesis. At the end we gain four concluions.
