请教达人关于密封圈的问题

auron_dash

关于密封圈压缩后加载压力，环境是ANSYS11.0。GUI如下：
Preprocessor->element type->add/edit/delete->add->hyperelastic->2D 4node 182
Preprocessor->Material props->material models->structural->nonlinear->elastic->hyperelastic->
mooney-rivlin->2 parameters,参数C10=1.87,C01=0.47.
Preprocessor->modeling->create->areas->circle->solid circle  画圆点为（0，0），半径为0.003425的圆
Preprocessor->keypoints 画点5（-0.005,-0.003425）,6(0.003425,-0.003425),
7(0.003425,0.002775),  8(0.005, 0.002775),
9(0.006,0.003425), 10(-0.006, 0.003425)
Preprocessor->lines->lines->straight line  连接56，67，78，910
Preprocessor->meshing->mesh->areas->free   划分圆
Preprocessor->modeling->create->contact pair->contact wizard  选所有的线为刚性体，圆为柔性体，接触为面－面接触，磨擦系数设为0.2，改变不正确的接触方向
Solution->analysis type->new analysis->static
Solution->analysis type->sol’n controls    basic中analysis option选的large displacement static
Number of substep=40 max=60 min=10
Solution->define loads->apply->structural->displacement->on lines 线56，67，78ALLDOF=0，线910UX=0,UY=-0.0005
Solution->load step opts->write LS file    设为一号载荷
Solution->define loads->apply->structural->pressure->on lines 加载在圆的左半线上，数值为20Mpa
Solution->load step opts->write LS file    设为二号载荷
Solution->solve->from LS files          starting LS file number=1 ending LS file number=2
开始计算
一号载荷可以计算成功，二号载荷不行，错误说要增加子布来缓慢加载，我增加到1000了还不行，不知道什么原因，麻烦达人帮我看看是什么原因，
谢谢了

是不是出现了严重扭曲呢？？

施主  我悄悄问一下
Preprocessor->element type->add/edit/delete->add->hyperelastic->2D 4node 182
Preprocessor->Material props->material models->structural->nonlinear->elastic->hyperelastic->
mooney-rivlin->2 parameters,参数C10=1.87,C01=0.47.

定义两系数mooney-rivlin模型  只指定c10 c01  怎么没有指定d呢  谢谢

是不是d＝2/k啊？？？
