Block Label Property in Stress Analysis
On this page, enter components of elasticity tensor: Young's
moduli, Poisson's ratios and shear modulus. Leave None or blank in any
Young's moduli box to specify that the block with the corresponding label is
excluded. With isotropic material, only two components of a tensor are independent.
To define orthotropic properties, first check the Anisotropic box.
Have sense for anisotropic materials or compound (sliced) materials modeled as
orthotropic. Specify Cartesian or Polar according to the class of
symmetry of anisotropy.
Displacement, Strain and Stress
Enter coefficients of thermal expansion here. To define variant coefficients in
different directions, first check the Anisotropic box. Normally, you specify
also the temperature difference between strained and strainless states. With coupled
problems, where the temperature of strained state is obtained from thermal analysis,
you should specify the temperature of unstrained state.
Enter components of body force density here. Body force vector components can depend on coordinates. To specify coordinate-dependent loads, enter the required formula in place of numerical value. Formulas are discussed in details in Working with Formulas section.
Specify Cartesian or Polar according to the class of symmetry of
anisotropy of thermal expansion or body force.
Allowable stresses are only used in
postprocessing stage to calculate the Mohr-Coulomb,
Drucker-Prager, and Hill criteria. You don't need to define allowable stresses,
if these criteria are of no interest to you. To define different components, first
check the Anisotropic box.
Have sense for orthotropic materials. Specify Cartesian or Polar
according to the class of symmetry of anisotropy.
