1)  failure model of tension-shear
拉剪破坏
1.
Based on some theoretical research,nonlinear finite element analysis by ANSYS on externally bonded FRP single shear model has been done,with a large plate to concrete width ratio,the effect of the ultimate strength of the failure model of tension-shear are explored.
拉剪破坏,是表面粘贴FRP加固混凝土单剪试件的一种重要破坏模式。
2)  diagonal splitting failure after longitudinal reinforcement yielding
弯曲剪切受拉破坏
3)  Punching failure
冲剪破坏
4)  compression-shear failure
压剪破坏
1.
The compression-shear failure of steel fiber reinforced concrete(SFRC) was studied by varying compressive stress and steel fiber content.
通过改变压应力和钢纤维掺量,研究了钢纤维混凝土的压剪破坏,结果表明:钢纤维混凝土压剪破坏后具有明显的材料软化特征,可用双线性剪切软化曲线表示;钢纤维混凝土压剪强度与其压应力和钢纤维掺量有关,但该两者的增强效果并不叠加。
5)  direct-shear failure
直剪破坏
1.
Based on the soil-structure interaction in one dimensional case and Timoshenko beam theory,a numerical approach for prediction of the dynamic responses and failure modes of structure under impulsive loadings is established by finite differential method,incorporating with the flexural and direct-shear failure criteria.
本文以常规武器爆炸荷载作用下土中浅埋钢筋混凝土框架为研究对象 ,将迎爆面构件简化为梁 ,基于一维情况下土与结构相互作用和Timoshenko梁理论 ,并引入梁的弯曲和直剪破坏准则 ,通过采用有限差分方法 ,建立了常规武器爆炸荷载作用下土中浅埋梁的动力响应和破坏模式分析方法。
6)  shear compression failure
剪压破坏
1.
The experimental results show that the behavior of the shear compression failure mode is quite different from the diagonal tension failure mode although both shear failure modes are sudden and brittle.
0是斜拉破坏和剪压破坏的过渡区。
补充资料:弯曲破坏
分子式:
CAS号:

性质:材料在弯曲负荷作用下,产生的破坏或断裂。实际应用中构件的弯曲破坏往往是复杂的,但作为材料的特性检验,可通过三点式弯曲或四点式弯曲试验来测定其弯曲破坏强度。对于塑料材料的静态法测定,一般采用三点式弯曲试验。若欲知其动态弯曲特性,则往往采用弯曲疲劳试验,它在复合材料试验中运用较多。它是对试样施加周期性的弯曲负荷,测量材料随循环次数增加的破坏情况。
