Abaqus做仿真时，遇到错误：errors:*elastic, type=shear must be used in conjunction with *eos to define the volumetric response of the material 明明都已经定义过shear modulus，仍然出现这种错误是什么原因啊？

已定义剪切模量仍报错要求定义，已粘贴inp文件*Material, name=explosive*Density1717.,*Elastic, type=SHEAR3.5e+09,*Eos, type=IGNITIONANDGROWTH, detonation energy=10200.7.781e+13, -5.031e+09,     0.8938,       11.3,       1.13。。。。。。。。。。。。。。。。。。。。。。。。。*Material, name=steel*Damage Initiation, criterion=JOHNSON COOK0.05,  3.44, -2.12, 0.002,  0.61, 1793.,  300.,    1.*Density7830.,*Elastic, type=SHEAR7.7e+10,。。。。。。。。。。。。。。。。。。errors:*elastic, type=shear must be used in conjunction with *eos to define the volumetric response of the material明明都已经定义过shear modulus，任然出现这种错误是什么原因啊？
