The finite element method is carried out to analyse the evolution of the stress intensity factor for cracks repaired with bonded hygrothermal aged composite patches. It is well known that the mechanical characteristics of a laminated composite diminish with the conditioning. In this paper, we use an

โฆ Synopsis
Stress intensity factor for an isotropic cracked plate with orthotropic patch reinforcement is calculated by the finite element method. Three-dimensional (3-D) elements are employed in the present study with the help of an adhesive element analysis performed in advance. Different finite element modellings of the interface bonding are made in the present 3-D analysis to show its effect in the calculation of the stress intensity factor of a patched plate with a crack.

The fatigue and fracture performance of a cracked plate can be substantially improved by providing patches as reinforcements. The effectiveness of the patches is related to the reduction they cause in the stress intensity factor (SIF) of the crack. So, for reliable design, one needs an accurate eva
In this paper, we investigated the crack growth behaviour of cracked thin aluminium plate repaired with bonded composite patch. The finite element method is used to study the performance of the bonded composite reinforcement or repair for reducing the stress concentration at a semicircular lateral n
