Endurica 2026-0301

Summary
This release includes a new example validating critical plane analysis against a series of cases involving combined tension/compression/shear loadings, studied originally by Cadwell and coauthors.  Error checking constraints on the volumetric parameters of the polynomial hyperelastic law were relaxed to admit negative coefficients.  It also includes improvements to the Ansys Mechanical and Abaqus CAE plugin interfaces, as well as several bug fixes.

Detailed changes

Features

• Added validation example from Cadwell et al for combined tension/compression/shear
• Ansys plugin:
  • Export temperature to ki format
  • Ability to create age and stiffness contours
• Reduced Polynomial: Allow D2 through D6 to be negative
• Update EIE for new fem_access_setup cmake function

Bug fixes

• Fix strain life map manual limits bug (previously, setting a limit beyond the data range did not change the axis limits).
• Fix Ansys plugin bug due to memory error when reading large .ko.json file
• Fix Abaqus CAE plugin bugs
  • when exporting hydrostatic stress to legacy hfi
  • when importing life and updated odb failed to open automatically
• Endurica DT – Stop concatenating the life results from previous ko file into the new ko file when using the –old-job option. This is consistent with all the other output requests.
• Fix bug for reduced polynomial model where the model was being IDed as neohookean when trying to write error messages which was causing a crash with no message printed.
