dc.description.abstractIn the current report, failure analysis for sub-interface cracks in composite materials has been carried through finite element method. A comprehensive numerical simulation on the parametric study of the stress intensity factor of the cracks has been done. The stress investigation is conducted by using Abaqus computer aided engineering (CAE) software. It involved creating a model with two cracks very near to the interface of two-phase composite material plate. A uniform tensile loading is applied to the composite plate. The stress intensity factor K1 at the crack tip is calculated through Finite Element Method. The value of stress intensity factor is obtained by finding the average value when uniform loading is fully applied. Stress intensity factor (SIF) is one of the main topics in Linear Elastic Fracture Mechanics, it is necessary to obtain the SIF value in failure analysis for engineering materials and structures. In this report, four main parameters - distance between the two cracks (in a line) to the interface, horizontal distance between the two cracks, crack length and material properties of the two materials involved, have been discussed to study their influence on the stress intensity factors of the cracks.en_US
