Finite Element Analysis (FEA) has become a cornerstone in the delamination analysis of laminated composites, employing various methods to predict and analyze the failure modes effectively. One of the primary methods used is the Virtual Crack Closure Technique (VCCT), which is well-established for its high accuracy and low computational time in simulating delamination in composite materials. VCCT is specifically developed for predicting the onset of delamination using the Strain Energy Release Rate (SERR) related to different delamination modes at the crack front. Another method, the eXtended Finite Element Method (XFEM), is recognized for its promising capabilities in predicting Mode I fracture, despite being relatively novel compared to VCCT. Additionally, cohesive zone modeling (CZM) is employed to simulate the delamination behavior in laminated composites. This approach involves inserting cohesive elements between bulk elements at each interlayer to represent the occurrence of multiple delaminations, effectively capturing the initiation and propagation of delamination under various loading conditions. The stabilized finite element method, inspired by the weighted Nitsche approach, is another innovative method designed to alleviate spurious traction oscillations at interlaminar interfaces. This method allows for the use of arbitrarily large values of cohesive stiffness without the traction oscillations typically observed with standard methods. Moreover, the finite element model has been utilized to characterize the effects of vibrational measurements for detecting delamination, offering a non-destructive analysis approach that aids in the rapid development of delamination-resistant materials. In the context of hole making in carbon fiber-reinforced plastic (CFRP) composites, finite element analysis (FEA) has been applied to understand delamination generation mechanisms and predict delamination initiation, establishing the relationship between thrust force and delamination. These methods, ranging from VCCT and XFEM to cohesive zone modeling and stabilized finite element methods, represent the common approaches in the finite element interface models for delamination analysis of laminated composites, each with its unique advantages and applications.Who are the scolars leading haptic glove actuation principles?

Composite laminate plates exhibit a variety of failure mechanisms due to their complex material composition and structural configurations. These mechanisms can occur independently or synergistically, complicating the prediction and analysis of failure in such materials. One primary failure mechanism is the development of various types of damage due to operational stresses, such as the weakening of the structure around geometric discontinuities like holes, which significantly affects the strength of carbon fibre-reinforced polymer (CFRP) plates. Additionally, fiber-reinforced polymers (FRPs) can experience different failure behaviors compared to metals, including fracture in unidirectional laminates, matrix cracking in cross-ply laminates, and delamination migration in multi-layered laminates. Delamination, particularly under static and fatigue loading, is another critical failure mode, where the propagation of delamination can be quantified using cohesive zone models validated against experimental data. Tensile failure, especially in laminates with thickness variations, can initiate from terminated plies in tapered regions, leading to delamination. The presence of defects such as holes and cracks can induce multiple failure modes, including delamination and fiber fracture, which are influenced by the laminate's layup. The inherent variability in composite materials, such as mechanical properties and fiber orientations, also contributes to the scatter in failure behavior. Different mechanical, thermo-mechanical, and hygro-thermo mechanical loads can affect the failure analysis outcomes for laminated composite plates, with the first ply failure load being significantly influenced by fiber orientation angles. Hybrid fabric-reinforced plastics, combining materials like carbon and Kevlar fibers, show varied mechanical properties and damage mechanisms due to anisotropy and the presence of geometric discontinuities. Delaminations, a common defect in composite laminates, can alter vibration parameters such as natural frequency and mode shape, affecting the laminate's dynamic response.
