The aerospace industry uses composite multi-hat stiffened panels for skins because of their high strength-to-weight and stiffness-to-weight ratios. However, laminated composites with initial flaws are susceptible to delamination under buckling loads.

The high strength-to-weight and stiffness-to-weight ratio materials, such as laminated composites, are advantageous for modern aircraft. Laminated composites with initial flaws are susceptible to delamination under buckling loads. PDA tools help enha

A stability analysis of laminated beam structures subject to subtangential loading, a combination of conservative and nonconservative tangential follower loads, using the dynamic criterion is performed. These loads are characterized using a nonconser

Because of the inherent complexity of fiber-reinforced laminated composites, it can be challenging to manufacture composite structures according to their exact design specifications, resulting in unwanted material and geometric uncertainties. Thus th

A new strength-fracture model is proposed for the formulation of decohesion elements, which are implemented in finite element models to predict failure of bonded joints. The proposed model unifies criteria for strength to predict failure initiation a

A 21 degree-of-freedom element, based on the FSDT, is derived to study the response of unsymmetrically laminated composite structures subject to both static and dynamic problems. In the FSDT model used here we have employed an accurate model to obtai

Three models were developed to predict randomness in the free vibration response of unsymmetrically laminated beams: exact Monte Carlo simulation, sensitivity-based Monte Carlo simulation, and probabilistic finite element analysis (FEA). It is assume

Composites materials may exhibit a remarkable difference in material properties depending on whether the state of stress is tension or compression. This tension-compression discontinuity in material properties often leads to a nonconvergent finite el
