Research shows that: (1) JH-2 constitutive model can be used to simulate the concrete cutting. (2) The better damage parameters have been represented and verified against the results of experiments, which are the D 1 = 0.6 and D 2 = 0.1 in the JH-2 model of C30 concrete. (3) In ...

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...
最后是Nimbus的,改动比较大一些,但从结合模式看,仍属于series II,甚至可能就是BMS分子scaffold hopping而来。 下图是Nimbus分子32的model,左侧hinge区与Deucravacitinib或者BMS-986202等相似,中间是scaffold hopping部分,右侧三氮唑仍能保持在比较接近的位置 (见下下图与Deucravacitinib的叠合),仍然有与R738的HB。 Ni...
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 (也就是这里的series II)。 再看看代表分子的结合模式。 下图即是最advanced临床分子Deucravacitinib (有可能今年获批),左侧hinge...

展开更多 In order to study the deformation and damage of tunnel surrounding rocks under the coupling action of static and dynamic stresses,a tunnel model under the coupling action of ground stresses and blasting loads is established.Firstly,the JH2 constitutive parameters of sur...MORE 作者 吴波...
At the end there are defined the parameters for JH2 model. You can design your geometry, apply the discretization, apply materials and so on. Finally save/export your work as inp file. After that try to follow the original structure (copy/paste JH2 parameters). Let's assume that every...
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,...
