ABAQUS动力显式计算时这种关于材性提示的错误该怎么处理啊？
Failed to regularize material data for material USTEEL02-HPB300. Please check your input data to see if they meet both criteria as explained in "MATERIAL DATA DEFINITION" section of Abaqus Analysis User Manual. In general, regularization is more difficult if the smallest interval defined by the user is small compared to the range of the independent variable.
Failed to regularize material data for material USTEEL02-HRB335. Please check your input data to see if they meet both criteria as explained in "MATERIAL DATA DEFINITION" section of Abaqus Analysis User Manual. In general, regularization is more difficult if the smallest interval defined by the user is small compared to the range of the independent variable.
Failed to regularize material data for material C30. Please check your input data to see if they meet both criteria as explained in "MATERIAL DATA DEFINITION" section of Abaqus Analysis User Manual. In general, regularization is more difficult if the smallest interval defined by the user is small compared to the range of the independent variable.

首先要明白，执行分析时，Abaqus / Explicit不会完全按照用户的定义使用材料数据；为了提高效率，所有以表格形式定义的材料数据都会自动正规化。
材料数据可以是温度、外部字段、塑性应变等内部状态变量。对于每个材料点计算，材料的状态必须通过插值确定，并且为了提高效率，Abaqus / Explicit将用户定义的曲线与等间距点组成的曲线拟合。
为了克服这个问题，您可以：
-改变公差（可以使用特定的材料类型来实现）
-完全关闭正规化（可以使用特定的材料类型来完成）
-添加/删除一些材料定义数据行（始终有效）
调整公差操作：
Edit Material对话框，选择General→ Regularization，即可重新定义公差。
