关于混凝土损伤塑性参数的输入

建好模型后，检查出现以下错误：
*NO TENSION or *NO COMPRESSION options may not be used with Plastic, Creep or Viscoelastic options
DURING THE CONVERSION FROM CRUSHING TO PLASTIC STRAIN Abaqus FOUND NEGATIVE AND/OR DECREASING VALUES OF PLASTIC STRAIN. VERIFY THAT THE DEGRADATION DATA UNDER *CONCRETE COMPRESSION DAMAGE IS CORRECT
DURING THE CONVERSION FROM CRUSHING TO PLASTIC STRAIN Abaqus FOUND NEGATIVE AND/OR DECREASING VALUES OF PLASTIC STRAIN. VERIFY THAT THE DEGRADATION DATA UNDER *CONCRETE COMPRESSION DAMAGE IS CORRECT
我的模型用的C60的混凝土，混凝土单轴受压应力应变曲线，我是照规范给出的公式自己计算出来的。如图，
