Simulating damage and delamination in fibre metal laminate joints using a three-dimensional damage model with cohesive elements and damage regularisation

Experimental and numerical investigation on bolted joint in glass–fiber reinforced composites

“…It should be mentioned that the failure criterion to predict the progressive failure of bolted joint composites has been discussed in previous literatures. [12][13][14][15] In fact, due to the limitations of molding process, specimens in the above-mentioned studies are usually prepared under high pressure. For the larger composite structure, the high pressure prepared technique cannot be used in practice, while the VARI process was feasible [16].…”

Effect of Resin Rich Veil Cloth Layers on the Uniaxial Tensile Behavior of Carbon Fiber Reinforced Fiber Metal Laminates

“…To consider the influence of various damage mechanisms on the performance of FMLs, it is necessary to consider progressive damage models in FE analyses. The material constitutive models based on continuum damage mechanics (CDM), assuming both degradation and linear elastic behavior of the composite layers in FMLs, have been employed by a few to study progressive damage simulations of FMLs [34][35][36]. Lapczyk [34] developed a two dimensional (2D) progressive damage model adopting the continuum damage mechanics (CDM)-based linear material degradation factors to study the response of FRP laminates.…”

A three dimensional implicit finite element damage model and its application to single-lap multi-bolt composite joints with variable clearance

“…Experimental approaches have been widely used for such studies [1][2][3][4][5][6][7][8][9], while numerical simulations of increasing sophistication are enhancing our understanding of the often complex mechanical response. Recently, three-dimensional (3D) finite element (FE) models have been used to capture the non-uniform, through-thickness stress distributions [10][11][12][13][14][15][16][17], and models to predict the onset and growth of material damage have been incorporated [18][19][20][21][22][23][24][25][26]. The majority of these analyses used implicit FE solvers, which generally have difficulties in converging all the way to the ultimate failure point of CBJs [27], mainly due to the complexity of contact definition between bolts and a damaging laminate.…”
