Based on irreversible thermodynamics,plastic deformation totally coupled damage and the subsequent damage load surface,which are used in damage modelling by some authors currently,are found inappropriate.A damage potential is introduced and employed to determine the evolution direction of the generalized damage vector;the related damage flow mutiplier is derived by using the damage permissible domain and the energy equation.

从不可逆热力学出发,讨论了现行作法中将损伤演化与塑性变形完全耦合,以及引入后继损伤加载面的不妥之处.为解决这一问题,提出了与塑性流动势无关的损伤流动势,并籍以得到广义损伤矢量的演化方向,而损伤流动因子则由伤演许可域与能量方程所确定.

This paper presents a new method using the damage induction vector (DIV) and element assembled vector (EAV) by which the change of modes due to structural damage can be applied to determine the location and scale of damage in structures. The structural damage is located by computing the Euclidean distance between the DIV and its project to EAV. The damage is assumed to be due to one or more damaged elements. The type and scale of damaged element i can be described by element damaged vector h i={a i,b i,c...

This paper presents a new method using the damage induction vector (DIV) and element assembled vector (EAV) by which the change of modes due to structural damage can be applied to determine the location and scale of damage in structures. The structural damage is located by computing the Euclidean distance between the DIV and its project to EAV. The damage is assumed to be due to one or more damaged elements. The type and scale of damaged element i can be described by element damaged vector h i={a i,b i,c i}. The characteristic of this method is much less calculation. Finally, the effectiveness of the method is demonstrated by detecting the damages of the shallow arches.

通过引入损伤诱导矢量和元素位置矢量,作者构造一种采用模态测试数据诊断结构损伤的新方法。利用损伤诱导矢量能迅速排除无损伤元素,缩小识别范围。这里认为结构损伤是由一个或多个元素的损伤引起的,采用元素损伤矢量hi= {ai,bi,ci}描述元素i的损伤程度及类型。该方法构造简单,能大幅度降低计算量。文中以浅拱为例,给出各种损伤情况下的诊断结果,以说明其有效性。
