摘要
利用光塑性方法,根据材料相似性,分析了中心压实法闭合孔洞时,不同的砧宽比对孔洞闭合效果的影响及孔洞周围应变分布情况,得到最佳砧宽比。
Using photo - plastic method and the similarity of the material, the influence of the differ-ence tool - width ratio on closing hole and the strain distribution around the hole have been analyzed when the hole is closed by the center of pressure molding, and the optimum tool - width ratio has been obtained.
