“…The effects of delamination on buckling and post-buckling deformation and delamination growth have been studied extensively in the past (e.g. Yin et al 1986;Chen 1991). However, relatively few investigations were conducted to study the effect of delamination on vibration characteristics.…”

As the result of this work models of the ®nite cracked beam element, delaminated beam element, and also delaminated plate element have been developed. These models have been used for the analysis of the inuence of the fatigue cracks and delaminations on the dynamic characteristics of the constructions made of unidirectional composite materials. The method of modelling cracks and delaminations presented in this work enables its easy modi®cation according to speci®c cases of damage (i.e. oblique crack, two-side crack, inside crack, multiple delaminations etc.).The results obtained from numerical calculations of the presented models are in good agreement with the known in¯uence of damage parameters like: the position and the depth of the crack or the length and the position of the delamination on the natural frequencies. Simultaneously, a strong in¯uence of the material parameters on these changes has been observed, which does not exist in the case of isotropic materials.

“…Under compressive load, each sublaminate of delaminated region should resist its own buckling load. Owing to the reduced thickness of each sublaminate, exural stiness decreases [91]. Consequently, the critical buckling load is much lower than that of the virgin laminate.…”

For the purpose of returning to Earth And I do not call one a Brahmana on account of his birth or of his origin from (a particular) mother; (but) the one who is possessed of nothing and seizes upon nothing, him I call a Brahmana.The man who is free from anger, endowed with (holy) works, virtuous, without desire, subdued, and wearing the last body (antimasarira), him I call a Brahmana.The man who is not hostile amongst the hostile, who is peaceful amongst the violent, not seizing (upon anything) amongst those that seize (upon everything), him I call a Brahmana.Whosoever has passed over this quagmire dicult to pass, (who has passed over) revolution (samsara) and folly, who has crossed over, who has reached the other shore, who is meditative, free from desire and doubt, calm without seizing (upon anything), him I call a Brahmana.

“…One-dimensional bucking analysis of single delaminated composite laminate plates was studied by Chai et al [4], Bottega and Maewal [5], Simitses et al [6], Chai and Babcock [7], Yin et al [8], and Williams et al [9]. Kardomateas and Schumueser [10] investigated the buckling and post-buckling of beam plates by considering the effects of transverse shear.…”
