The conventional approach to analysis the buckling of rectangular laminates containing an embedded delamination subjected to the in-plane loading is to simplify the laminate as a beam-plate from which the predicted bu...
Based on the modified mixed Hellinger-Reissner(H-R) variational principle for elastic bodies with damping, the state-vector equation with parameters is directionally derived from the principle. A new solution for th...
The energy release rate(ERR) of crack growth as the energy change at the same time t between the two states of the structure is redefined, one is with crack length a under the loading σ(t), the other is the state wit...
The study on properly degradation of damaged,.onlj,osile laminates is extendedto anisotropic laminates with matrix cracking. In (II) of the paper, a solution forpartitioned stiffness is given to complete the consti...
The study on property degradation of damaged composite laminates is extendedto anisotropic laminates with matrix cracking. In (I) of the paper, an idea of 'stiffnesspatition' is proposed to deal with the puzzle that ...
Classical plate theory has been used to find out interfacial stress intensity factors in composite laminates. By using a well-known relation between the crack-tip energy release rate and the complex stress intensity f...
An interface crack analysis is presented for further understanding the characteristics of the crack-tip field. The conditions under which the energy release rate components would exist are emphasized and the relations...
A finite composite laminate weakened by multiple elliptical holes of arbitrarydistribution, arbitrary orientation and arbitrary dimension, is treated as an anisotropic,finite multiple connected thin plate. Using the c...
This paper presents the stress and strain distrihution obtained numerically in thethickness direction in the central region of symmetric composite laminates underuniaxial exlension and in-plane pure shear loading. It ...
