Finite Element Simulation of Interlaminar and Intralaminar Damage in Laminated Composite Plates Subjected to Impact

Abstract

Here In this study, the composite laminates subjected to transverse impact with consideration interlaminar and intralaminar damage based on Cohesive Zone Model (CZM) and Progressive Damage Model (PDM) are investigated by numerical analysis using ABAQUS commercial finite element code. The delamination in stacking ply with the same fiber orientation is considered as interlaminar damage and the delamination in an inner layer of any cluster is ignored. Hashin criterion is used for intralaminar damage initiation and evolution without using any subroutine. First, the appropriate procedure for delamination on composite specimen was suggested based on CZM approach in double cantilever beam to verify the intralaminar damage simulation. Then by considering several case studies with different impact energies, the results of present simulation is verified with the relevant and available experimental results and numerical references in the existing literature. According to the available experimental results the present simulation results are more acceptable and accurate than the results of similar numerical works, especially in higher impactor velocity.

Determination of fracture energy (mode I) in the inverse fiber metal laminates using experimental–numerical approach

“…To sum up, the cohesive elements approach gives more control over simulations and more possibilities, but the cohesive surface approach can be as good as the cohesive element and often is far more effective in terms of time and complexity. For example, Soroush et al (Soroush et al 2018) indicate that threedimensional analysis using cohesive surfaces decreases computational significantly. A three-dimensional analysis can capture the nonlinear progression of delamination front (through the width of the specimen) (Alfano and Crisfield 2001).…”

“…A three-dimensional analysis can capture the nonlinear progression of delamination front (through the width of the specimen) (Alfano and Crisfield 2001). Examples of three-dimensional analysis of delamination can be found in Alfano and Crisfield (2001); Alfano et al (2007); Bieniaś et al (2017), and in Soroush et al (2018); Alfano and Crisfield (2001) for a cohesive surface approach. In a two dimensional analysis, the crack front progression is assumed to be the same through the specimen width.…”

“…In a two dimensional analysis, the crack front progression is assumed to be the same through the specimen width. However, this simplification does not have a significant influence on the results, and this approach was used with good results in Soroush et al (2018); Ning (2015); ASTM International 2001).…”

Numerical and digital image correlation analysis of tensile behavior of thin-ply hybrid laminates with discontinuous carbon sandwiched by continuous glass and carbon

“…18 Finite element analysis (FEA) is a numerical model that has been widely used in the study and prediction of failure in composite materials. Finite element analysis can predict and analyze either interfacial damage initiation and progression using cohesive zone modeling (CZM), 19 fiber damage initiation, and evolution using the Hashin damage criteria, 20 or generally the stress–strain response of composites. 19-23 FEA has also been applied in the analysis of nano and micro-fiber reinforced composites, 24 whereby they used the shear lag model to predict interfacial shear strength in nanocomposites.…”

Finite element modeling ofCFRPcomposite tubes under low velocity axial impact

“…Various aspects of modeling low velocity transverse impact were discussed in. [ 10–15 ] The validity of several techniques for modelling a transverse impact was analyzed by Khalili et al [ 10 ] when focusing on the finite element type, impactor model, and solver type. Tita et al [ 11 ] and Sellitto et al [ 12 ] show that the 3D stress state of the solid elements gives more accurate predictions of the experimental tests in comparison with models with shell elements.…”
