uses the JH-2 model.The JH-2 model assumes that the damage variable increases progressively with plastic deformation.The material parameters used for the JH-2 model are listed inTable 2.1.18–4. The JH-2 model similarly consists of three components. 结果如下: impactsiliconcarbide_jh2.txt 把...
JH-2 modelNumerical simulationIn order to investigate the application of JH-2 (Johnson-Holmquist-2) constitutive model in concrete, a series of parameters study have been conducted to evaluate the JH-2 model in C30 concrete. The finite element analysis software ABAQUS is utilized to simulate the...

This report describes the implementation of a fully three-dimensional rate, pressure, and damage-dependent constitutive model for brittle materials such as ceramics into the explicit, Lagrangian finite element code DYNA3D. The model, otherwise known as the Johnson-Holmquist II (JH-2) ceramic model,...
2本构完整强度方程主要涉及a、n、t、c四个待测参数,其中a为完整强度参数,n为完整强度指数,无实际物理意义;t为最大拉伸静水压,是完整强度曲线与横坐标轴的交点,无法直接测试获得;在传统参数获取方法中,通常将材料抗拉强度作为t的近似取值,或者按照模拟调试结果自行定义t的取值(如文献“dynamic material model of ann...
下图是“缘起”分子model,大环化的分子能很好保持原先binding pose。因此无意外能与BMS分子 (橘色) 很好叠合 (下下图)。 Alumis一个专利分子的model 前面BMS橘色分子与Alumis粉色分子的叠合 Series II 各公司专利及代表分子的结合模式 首先先看一下BMS自己的专利,下面两张图,主要保护的是他们的临床分子系列 (也就...
