However, tensile strength is less affected by multiple delamination.
Additionally multiple delamination analysis of a composite specimen is also presented.
Additionally multiple delamination analysis of a composite specimen is also investigated.
A localized sub-plane control strategy is adopted for tracking multiple crack formations and the propagation of multiple delamination fronts.
Upon a successful partition of the total energy release rate into individual modes, a mixed mode delamination propagation criterion has been employed for modelling delamination propagation, which is also applicable to multiple delamination problems.
A simple multiple delamination model developed by the authors earlier is employed to take care of any number/size of delamination located anywhere in the laminate.
An improved Xu and Needleman's CZM and a bilinear CZM are used to study multiple delamination growth comparatively.
In the present paper, a sub-laminate-wise constant shear kinematics with multi-point constraints (MPC) in frequency domain is used to model the interface between multiple delaminations or strip inclusions and the base-laminate.
The examples include models containing single and multiple delaminations and growth in the presence of buckling.
The exact analytical solution of buckling in beams with multiple delaminations is presented.
