其实这两种分析步最大的区别就是分析过程是不是受到速率的影响。Static, General中不用考虑到物体的density、rate等物理意义，假如填入对计算结果也没有什么影响。而density、rate等物理意义是Dynamic, Implicit必须要考虑的、至关重要的物理量；还有他们对时间的定义也不一样——staitc, general的时间并不...

本课程详细讲解了在ABAQUS中模拟多体动力学分析,介绍了connector、interaction及方程约束的使用方法。本案例中采用的Dynamic Implicit分析步,在模拟复杂多体动力学中具有较大的优势。本案例旨在较为全面的介绍ABAQUS中动力学约束及边界条件联合应用技巧及所需要注意的问题。
The explicit scheme is used for the effective aging time and the temperature, while the implicit scheme is used for the strain and strain rate. This means that we freeze the values of ta and T when performing the return-mapping to identify the increment in equivalent plastic strain in an ...

Both implicit and explicit schemes for time integration were used. These characteristics are grouped into Solver in Table 4. Higher rates of loading can lead to temperature effects which can be modeled through the inclusion of energy balance. The Coupling label differentiates between the inclusion of...
I was wondering if anyone has modeled surface based cohesive behavior in 2D in Abaqus/Standard using *Dynamic, Implicit? I have modeled a thin film which is in contact with a discrete rigid surface using cohesive surface interaction. Another rigid surface impacts the film at a velocity. I am...
