摘要
探讨经典塑性理论存在的问题 ,讨论能考虑屈服区域内弹性体应变的一弹塑性问题解法 ,分析弹塑性裂纹和非裂纹问题 。
An analogy scheme for determining elastic-plastic crack-tip fields, is tried to solve non-crack problems. Different to classical plastic theory, the attention of the scheme is focused on elastic volume deformation in plastic zone. Both crack and non-crack solutions are discussed and checked by the finite elements, it is concluded that the fields developed by this analogy scheme is more physically reasonable.
