摘要：This paper present the Sequential Coupled Thermal - Structural Analysis to investigate the associated thermal stresses and deformations under simulated operational conditions close to the real situation on different materials. Analysis carried out by reference environmental testing conditions; in different ambient temperatures on different materials i.e. cast iron, structural steel.The finite element analysis software ANSYS Workbench 14.0 used to calculate the linear steady state temperature distribution under the thermal field & structural analysis. Thermal analysis calculates the temperature distributions and related thermal quantities in an exhaust manifold. Structural analysis takes inputs from thermal analysis to calculate deformation, stress and strain. FEM analysis is done by using tetrahedral element of first order and convergence test is performed for structural load. The purpose of this analysis is to ensure the appropriateness of material for the defined design from the view point of serviceability of the exhaust manifold. Selected details and results of the overall investigation are presented and discussed within the framework of this paper
