采用材料在受力变形过程中耗散的塑性应变能定义材料的延性损伤变量,可以克服现有延性损伤变量定义的局限,完整描述材料在廷性损伤全过程中的损伤变化情况;实测方便,精度易于保证;还建立了相应的损伤演化方程和损伤材料的应力-应变本构方程,由其获得的损伤准则等价于第四强度理论。
补充资料：大剂量增强后延迟CT
大剂量增强后延迟CT
CT检查方法之一。用于检查肝脏占位性病变的增强CT技术。使用总量为60g碘的经尿路排泄的对比剂，经静脉注入后延迟4～6小时后进行CT扫描。该法不同于一般在增强后5～15分钟的延迟扫描。主要原理是：注入的对比剂中约有1%～2%将滞留于正常肝实质内，最后经胆道排泄，从而使正常肝组织的密度值比平扫时增高约20HU，而肝内病灶区内无对比剂滞留，表现为低密度，形成对比。应注意的是此时肝内血管亦无对比剂滞留而呈低密度，因此需结合增强CT(包括普通增强、动态团注增强或血管造影CT)比较判断。该法可使肝内小占位性病灶的检出率提高约20%～30%。
