Abstract

In the present work, an analysis of crack propagation in a rectangular plate made of two different materials viz. Titanium and Titanium Aluminide using FEM approach is carried out. Titanium forms an important constituent of Landing Gear application in aircrafts. The analysis is performed on four different contours viz. circle, square, rhombus and hexagon [1]. The tensile load is applied at one side of the quarter plate under symmetrical boundary conditions which results in opening mode of crack. The crack is initiated normal to the applied tensile load at the region of stress concentration. One of the best indicators of crack propagation rate, i.e. Stress Intensity Factor (SIF) is determined using Finite Element software. It is seen that the theoretically calculated values of SIF are in good agreement with each other. It can be concluded from the work that Titanium can be replaced by Titanium Aluminide considering cost, weight and other parameters.
