Abstract

Analysis of stress intensity factors of crack branching were studied on the difference plate ratio with an initial edge crack branching under tensile load using finite element method. Variation of main crack length, crack branching length, and crack branching orientation are investigated. It was established that crack branching occurs when there is instability of stress at crack-tip area. In most cases, crack will branch out with symmetrical form. It is in appropriated that one important parameter to analyze the condition of stress at crack tip is stress intensity factor. Stress intensity factors then are obtained by using the method of finite element. Simulation result using finite element method show that KI is proportional with main crack length and crack branching length. Orientation of crack branching is dependent on another parameter. KI is inversely proportional with the ratio of length-width plate
