Abaqus Thermal Stress Analysis Skills

Overview

This skill module provides specialized skills for Abaqus thermal stress analysis to analyze thermal stress and deformation caused by temperature changes. Includes steady-state heat transfer, transient heat transfer, and thermal-mechanical coupling analysis.

Skills List

1. Thermal Stress Analysis (skill_thermal_stress)

Analyze thermal stress and deformation caused by temperature changes, including sequential coupling and fully coupled methods.

Applicable Scenarios:

• Welding residual stress analysis
• Thermo-mechanical coupled loads
• Deformation caused by temperature gradients
• Thermal shock analysis

Code Snippet:

# Heat transfer step
model.HeatTransferStep(
    name='Steady-State',
    previous='Initial',
    response=STEADY_STATE
)

# Thermal expansion material
material.Expansion(table=((expansion_coeff,),))

# Import temperature field from ODB
model.Temperature(
    name='Temp-From-ODB',
    createStepName='Thermal-Stress-Step',
    region=region,
