Initial Stress and Strain
You can add the Initial Stress and Strain subnode to the Elastic Wire, in order to specify the force or strain state in the structure before applying any constraint or load. The values given are not initial values in the mathematical sense, but rather a contribution to the constitutive relation
Initial Stress and Strain
Enter an Initial axial strain en0 and Initial axial force Ni.
For details about initial stresses and strains, see Stress-Strain Relation.
