　　The aim of this paper is to improve the rolling contact wear and fatigue resistance of ferrite-pearlite wheel steel by laser dispersed treatment.Such treatment creates isolated glazed regions on the surface layer of wheel steel,which are composed of fine martensite and retained autensite and have an average hardness of 762HV.

基于BS7910标准评定高速列车底架缺陷安全性

本文通过对高速列车底架中A7N01铝合金焊接接头进行应力测试及静拉伸试验，借助于有限单元法求解焊接接头中的应力场强度因子，采用BS7910方法对A7N01铝合金焊接接头中表面半椭圆裂纹和单边穿透裂纹进行安全性评定。结果表明，单边穿透裂纹比表面半椭圆裂纹危险得多。

焊接结构疲劳断裂仿真及寿命评定

传统强度设计思想的一个基本假设是把材料的初始状态视为无缺陷的均匀连续体。事实证明，根据这一思想设计的构件并不能保证其服役的安全可靠性。断裂力学通过连续介质力学的理论分析建立含裂纹构件的强度设计概念，提出设计计算方法及物理实验模型，探讨如何控制和防止结构的断裂破坏。
