![]() Factor of stress intensity are calculated using expansion of the M-integral method by the embed in France 3D/NG. The interact between thermal and mechanical loads acting on the framework at a specified place structural reaction to approach the crack extremely is accounted for by employing a structure sub modelling and interpolation tactics. Final result got through the analysis of thermal structural fracture mechanics. The present data were taken from typical turbine blade used to run a heat transfer analysis and study of thermal structural analysis. ![]() The analysis was made under combined loads of thermal and mechanical loads. Geometry derived a model was used for finite elements model and Crack simulation have been computed. A study model the 2D ANSYS auxiliary thermal/structural model was created to facilitate sensitivity study. The work is presented through this methodology simulating cracks gradation in the surface of texture of the walls of turbine blade. The main aim of this work to assessment for damage tolerance of framework by using computational mechanics software. 108-119 © IAEME: Journal Impact Factor (2011): 1.2083 (Calculated by GISI) IJMET © I A E M E International Journal of Mechanical Engineering and Technology (IJMET), ISSN 0976 – 6340(Print), ISSN 0976 – 6359(Online) Volume 3, Issue 2, May-August (2012), © IAEME 109 out by using FEA simulation tools and the same option is tested by experimentally by fabricating the real component is explained in this paper.

The presence of thermal gradients will cause stress, strain, and deformation in the components which in turn cause changes in the functional performance of MUX.To eliminate these effects of thermal expansion and provide stable RF performance over the range of operating temperature a technique called temperature compensating mechanism is proposed.Also to reach up to the present need the Conventional MUX made from Invar material has higher cost and heavy weight with lower operating temperature range up to 140 watt power is replaced by light weight Novel multiplexer has operating temperature range as high as 250 watts to 400 watts. Thermal expansions/contraction occurs due to heat dissipation and material property variation. ![]() When RF energy is passed inside the cavity heat is dissipated in the cavity. These filters operate in high temperature environment which are seen in operating life time of the satellite in space. To reach up to the present need development of the high power application multiplexer for satellite communication system which provides stable RF performance over operating temperature range is essential.Thispaper work deals with one of the satellite component, which is called as multiplexer (MUX).The performance of the MUX depends on the dimensions of its components. The graphical results are presented for various positions of delamination, equivalent TNT mass and delamination area ratios. The numerical results show that delamination presence within the layered composite decreases the protective capacity of the structure to explosion charge. The delamination model using finite elements and interfacial constrain conditions are presented. The spatial pressure variation is determined by using Friedlander exponential decay equation. ![]() The methodology for the blast pressure charging and the mechanism of the blast wave in free air for a layered plate belonging to a ship hull structure are given. A nonlinear analysis with the finite-element computer code COSMOS/M was done. Various scenarios (parametric calculus) to evaluate the behavior of the layered composite plate to blast loading are presented: position within the thickness, delamination area per plate area ratio, charge weight. The explosion center is considered to be placed in the close proximity of the plate. Main objective of this analysis is to investigate the effect of the central circular delamination parameters on the layered composite plate behavior during the blast load in air. Results of the study concerning the protective capacity of delaminated layered composites subjected to an explosion of a spherical charge are presented in this paper. ![]()
