解决方法是使用enhanced hourglass controls,mesh refinement和penalty contact,以便接触可以更好地分布在节点上。 (2)如果单元是reduced integration的,需要对比atificial energy ALLAE 和 internal energy ALLIE,以确保用于约束hourglassing modes的artificial energy没有超过限制。 (3)在Explicit中,hexahedral单元是否有足够多...

For a model to be in static equilibrium, the net force acting on each node must be zero; i.e., the internal and external loads at each node must balance each other. For node athis equilibrium equation can be obtained as follows. ...
