Heat Transfer Analysis
Services
We undertake thermal stress analysis for a range of problems using finite element analysis. Thermal growth of piping, structures, and components can be prevented using our specialist modelling techniques under steady state or transient conditions. Concerns relating to thermal creep or yielding can also be addressed using our modelling techniques.
Asset Integrity also provide services which compliment thermal stress analysis, such as finite element analysis (FEA), structural analysis, dynamic stress and fatigue analysis, and pipe stress analysis and design.
About Heat Transfer & Thermal Stress Analysis
Causes of component or structural failure can be attributed to thermal stress. Thermal stresses are primarily developed due to temperature differences across a component or structure, which can lead to thermal creep or yielding of the material and subsequent failure.
Thermal analysis, using finite element techniques, can be carried out as steady state or transient analysis.
