Stress & Fatigue Analysis For Piping, Valves, Vessels, Heat Exchangers

Stress and Fatigue Analysis for Thermal Transient Loaded Mechanical Components Gantner Instruments engineering service provides stress and fatigue analysis for thermal transient loaded components of power plants or other industrial plants and applications. Stress & Fatigue Evaluation According to Codes & Standards: SME Section III NB3200 A CC-M B3200 R TA 3201.2 / 3211.2 K UREG / CR-6909 N Thermal Load Definition Based on thermal loads gathered by the process automation system or dedicated monitoring system, transients for the a nalysis are created. In case input data from the normal process...

Finite Element Software For the thermal and mechanical analysis a detailed finite-element model is created. Mechanical Analysis The thermal transient field of the analyzed pipe or component is used for the stress & strain calculation. The complete stress tensor (normal & shear stress) is evaluated and stress ranges according to Tresca or von Mises are determined under consideration of plasticity factors, weld seam factors in compliance with the codes & standards. Stress is linearized on evaluation sections, the comparison with the allowable stress limit will inform if an elastic (Ke=1) or a simplified...
