As far as a plane-strain problem with crack propagation is concerned, the previous ex- perimental investigations of the elasto-plastic crack tip field on ductile aluminum alloys using moue interferometry showed the possible existence of anisotropic strain hardening behavior in this field, which is often described as of isotropic plasticity.
基于垂直和平行于裂纹线的实测对数位移场的斜率不同,在裂纹尖端附近假设存在由大塑性变形导致的各向异性应变硬化。
These include variants of papillary thyroid cancer(PTC) such as insular carcinoma(IC),columnar cell variant(CCV),the tall cell variant(TCV),as well as diffuse sclerosing variant(DSV),and Hürthle cell carcinomas.
随着对甲状腺癌认识的深入,出现了几种特殊变异类型,其侵袭性位于分化型和未分化型甲状腺癌之间,叫中间分化型甲状腺癌,分为甲状腺高细胞型变异(TCV),柱状细胞型变异(CCV),弥漫性硬化性变异(DSV),岛状细胞癌(IC)和H櫣rthle细胞癌。
