The influence of back pressure on the J-integral,the ligament section variables and the separation force are researched through the numerical simulation of the fracture splitting process with back pressure.
通过数值模拟与实验相结合的方法对准静态加载条件下的连杆裂解过程进行分析,确定了C70S6连杆裂解的临界J积分值,并对背压裂解过程进行数值模拟分析,对背压力对于连杆裂解J积分、韧带区场变量及裂解力的影响进行探索。
