Detection of Delamination Between the Plate Layers Manufactured From Composite Materials الكشف عن الانخلاعات بين طبقات اللوحة المصنعة من المواد المركبة

Abstract

In the present work, analysis of delamination between the layers plate of composite materials is studied. Numerical solution using ANSYS finite element programs (Mechanical APDL 15.0) , It is a general purpose finite element modeling package for numerically solving a wide variety of engineering problems. These problems include static/dynamic structural analysis (both linear and non-linear), heat transfer and fluid problems, as well as electro-magnetic problems. In our work, we used it to investigate the effect of strain nonlinearity on the mechanical response of these plates.The results show a good agreement between nonlinear analysis and experimental work,for composite laminated plate with delamination, the maximum discrepancy between nonlinear natural frequency and experimental work (10.87%) for (CCCC) boundary condition.
