Abaqus/Standard nonlinear package thermal-stress analysis

Dassault Systèmes SIMULIA · Thermo-mechanical simulation and lifetime prediction

Purpose: Package thermal-stress analysis may require nonlinear models for plasticity, viscoelasticity, creep or contact. Abaqus/Standard provides a general solver for building and validating these models.
Technical approach: Its implicit finite-element capabilities cover nonlinear structures, heat transfer and thermal stress, with material, contact and user-subroutine options.
Scope of use: BLNKK lists it as a candidate for package warpage and interface-stress studies. General capabilities do not validate accuracy for a particular package.
Limitations and open questions: These evaluation considerations are compiled by BLNKK from public information. They are not supplier guarantees or a mandatory submission checklist.
Scope and limitations
Solver features do not establish model validity. Confirm current-release and license availability separately from the historical datasheet.
What to prepare
BLNKK suggests preparing geometry, thermal history, material-property data and measurements for calibration. Required inputs depend on the model.
Confirm with the supplier
Confirm release, licensing, material models, user-subroutine support and technical assistance. Discuss model validation and mesh convergence.
Public evidence: The current page documents solver capabilities. The attachment is the historical Abaqus/Standard 6.14 datasheet from 2014.
