“…It is significant from the figure that energy release rate attains lower value for large bimodular ratio, which is in good agreement with the results cited in paper. 70 Diagram reveals that G T is very low and approximately same for R = 4 and 5 for all values of u x . Low energy release rate indicates the retardation of interfacial failure propagation rate of the structure.…”

In the present work strain energy release rate as a fracture parameter has been used to evaluate the skin-stiffener debonding in stiffened composite panel with functionally graded (FG) bimodular material property under thermomechanical coupled field. The influence of ply lay-up and interaction of residual thermal stresses on the skin-stiffener has been investigated. Stress-dependent elasticity problem of bimodular stiffened panel made up of laminated fiber reinforced polymeric composite is carried out using finite element analysis under various bimodular ratios. The numerical result in terms of compressive load as a function of applied displacement has been compared to the existing literature data to assess the effectiveness of the implemented methodology. Variation of energy release rate along the interface delamination front has been plotted for both mechanical and thermo-mechanical coupled loading with modulus ratio R varying from 1 (unimodular) to 5. Asymmetric variation of energy release rate along the interfacial front has been observed for the bimodular stiffened composite panel.

“…Adhesives are being used extensively in various industries due to their noticeable performance. Moreover, fracture characterization of adhesives received a great deal of attention by researchers [1][2][3] and enhancement of interfacial properties is one of the key research topics in this community [4][5][6]. The peel test is one of the most frequently used method to assess the interfacial mechanical properties between adhesive and adherend, and the peel strength is a measure of the force required to separate the peel arm from a substrate [7].…”

With the aim of understanding failure modes in the peeling of silicone-based adhesive joints and, in particular, the occurrence of adhesive or cohesive failure, an experimental campaign has been conducted by considering plastic substrates with different surface roughness. A flexible strip has been bonded onto such substrates using a silicone adhesive, by controlling its thickness. Peeling tests with 90º and 180º peeling angle configurations have been performed and the effect of joint parameters, such as surface roughness and adhesive thickness, onto the adhesion energy and the failure mode are herein discussed in detail. Experimental results show that the failure mode varies in each peeling test configuration such that in the case of 180º peeling test there is mainly cohesive failure, while for 90º peeling angle, a combination of adhesive and cohesive failure occurs. Moreover, due to the presence of different failure modes in each peeling configuration, the substrate roughness can increase the adhesion energy only in 90º peeling tests.

“…A more detailed survey [13][14][15]18,19] indicates that although there is a large amount of literature available on the mechanical behavior of composite joints, most of these studies are only focused on the joints with regular geometry which generally comprise vertical and horizontal parts. Very few research works have investigated the integral joints with complicated assembly and geometry.…”

The research work in this paper is focused on studying the failure behavior of an integral π-shaped laminated composite structure subjected to a bending load. A progressive damage model based on the 3D Tsai-Wu failure criterion and a developed gradual degradation model was employed to simulate and assess the load-carrying capacity, the onset and propagation of damage, and the failure mechanisms. For this unique π-shaped composite structure, disbonding was found to be the dominant damage mode under bending load, and the approximate maximum load could be maintained for a brief time during the final failure due to the gradual loss nature of the load-carrying capacity. The extent of damage was found to be more serious on the side of Rib II compared to the other side.
