An analytic model for thermoelastic properties of composite laminates containing transverse matrix cracks

Nonlinear bending and postbuckling analysis of matrix cracked hybrid laminated plates containing carbon nanotube reinforced composite layers in thermal environments

“…In the above equations, the reduced stiffness matrices [ * (11) where A , B, etc., are the plate stiffness matrices, defined by (14) in which CN E 11 …”

“…These cracks are invisible but can affect both the material properties of FRCs and the mechanical behaviors of the plate. Many previous works [14][15][16][17] focused on the prediction of the stiffness reduction of FRCs due to the matrix cracking.…”

A spectral finite element for wave propagation and structural diagnostic analysis of composite beam with transverse crack

“…A majority of the methods developed for predicting the reduced properties of cracked laminates are applicable to only cross-ply laminates as discussed in [7]. Later Gudmundson and Zang [8] and Adolfsson and Gudmundson [9] developed models for equivalent degradation of the thermoelastic properties of laminate of more general conÿgurations. Here, the strain energy release rate as a function of the transverse crack density was used to obtain the change in elastic coe cients.…”

Bayesian model selection and parameter estimation for fatigue damage progression models in composites

“…A set of five model classes pertaining to three families of damage mechanics models [23] (i.e., shear-lag [24,25], variational [26] and crack opening displacement (COD) [27,28]) is chosen to represent the relation between the macro-scale stiffness reduction and the micro-scale damage, due to matrix-cracks. Damage mechanics models are preferred over other analytical approaches (e.g.…”
