On closing the constitutive gap between forming and crash simulation[C]//Proceedings of 10th International LS-DYNA Users Conference, Detroit, USA:LSTC, 2008:21-31.[10] BAI Y, WIERZBICKI T.
However rigidizing the whole vehicle for pre-crash simulation could be challenging since it will conflict with existing rigid body or constraint definitions.
工程界目前傾向于采用兩類策略:第一類是基于Drucker-Prager或Mohr-Coulomb這類原本用于巖土材料的屈服準(zhǔn)則,通過引入靜水壓力項(xiàng)來修正拉壓不對稱性;第二類則是采用專為聚合物開發(fā)的半解析模型,如SAMP-1(Semi-Analytical Model for Polymers)。
