Scalar Extract

This module extracts the displacement and strain components computed using the Digital Volume Correlation module.

Scalar_extract

Description:

To unify the local and global approach, the strains were defined in the same way according to the Green-Lagrange strain formulation.

Connections:

Data [required]:

The type of the scalar field to be extracted. Depending on the scalar field type, the ports are automatically adjusted. If the vector field is connected (.disp), the 3 vector components and the displacement magnitude are shown. If the strain tensor is connected (.strain), the 6 strain components of the Green-Lagrange strain tensor are shown. In addition, the most commonly used strain invariants, principal strains, and equivalent strain (von mises strain) are also active.

Ports:

  • Strain components: The 6 components of the Green-Lagrange strain tensor.
  • Principal strains: The 3 principal strains (e3 > e2 > e1).
  • Strain invariants: The 3 strain invariants.
  • Equivalent strain: The equivalent strain (von Mises strain) often used to describe the state of strain in solids.
