ABAQUS動力顯式計算時這種關于材性提示的錯誤該怎么處理啊？
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，執(zhí)行分析時，Abaqus / Explicit不會完全按照用戶的定義使用材料數(shù)據(jù)；為了提高效率，所有以表格形式定義的材料數(shù)據(jù)都會自動正規(guī)化。
材料數(shù)據(jù)可以是溫度、外部字段、塑性應變等內(nèi)部狀態(tài)變量。對于每個材料點計算，材料的狀態(tài)必須通過插值確定，并且為了提高效率，Abaqus / Explicit將用戶定義的曲線與等間距點組成的曲線擬合。
為了克服這個問題，您可以：
-改變公差（可以使用特定的材料類型來實現(xiàn)）
-完全關閉正規(guī)化（可以使用特定的材料類型來完成）
-添加/刪除一些材料定義數(shù)據(jù)行（始終有效）
調(diào)整公差操作：
Edit Material對話框，選擇General→ Regularization，即可重新定義公差。
