Modeling of crack propagation by a finite element method under mixed mode conditions is of prime importance in the fracture mechanics. This article describes an application of finite element method to the analysis of mixed mode crack growth in linear elastic fracture mechanics. Crack - growth process is simulated by an incremental crack-extension analysis based on the maximum principal stress c...

In the conventional static analysis of building frames, base is idealised on rigid supports and subdivided into three parts namely, superstructure, foundation ground soil, before design. real life situations, soil underneath undergoes deformations which may alter performance structure. this paper, it studied effect type response a frame system with both fixed flexible base. The Winkler model so...

In this paper, we apply the  homotopy analysis method (HAM) for solving fuzzy  linear systems and present  the necessary and sufficient conditions for the convergence of series solution obtained via the HAM. Also, we present a new criterion for choosing a proper value of convergence-control parameter $hbar$ when the HAM is applied to linear system of equations. Comparisons are made between the ...
