Delamination is detrimental to the composite materials, and it may occur in the manufacturing process of the unidirectional laminate of the spar cap in wind turbine blades. This paper studies the effect of different delamination defects on the strength of the unidirectional laminate. The finite element model of laminate with different delamination areas and delamination heights is established using solid elements. The eigenvalues of laminates have different parameters calculated based on the finite element method. The final coupon test is used to verify the conclusions of simulation results. The finite element method presented in this study shows excellent capabilities to predict the buckling behavior of the laminate. The buckling eigenvalue of tested laminate is negatively correlated with the delamination area and positively correlated with the delamination height under the edgewise load. The S11, which is too high at the boundary of the delamination region, plays a significant role in buckling failure. It has a particular reference value for testing the laminate of blade both in theory and practice.

The paper describes the Field Boundary Element Method applied to the fracture analysis of a 2D rectangular plate made of Functionally Graded Material to calculate Mode I Stress Intensity Factor. The object of the Field Boundary Element Method is the transversely isotropic plane plate. Its material presents an exponential variation of the elasticity tensor depending on a scalar function of position, i.e., the elastic tensor results from multiplying a scalar function by a constant taken as a reference. Several examples using a parametric representation of the structural response show the suitability of the method that constitutes a sight of Stress Intensity Factor evaluation of Functionally Graded Materials plane plates even in the case of more complex geometries.

“…The practical defect could greatly weaken the buckling-resistant ability of the structure because of defect sensitivity. For the cylindrical FGM shell with a local crack, Nasirmanesh and Mohammadi [31] investigated the buckling behavior under the axial tension, axial compression and coupled internal pressure/axial compression conditions using the extended finite element method (XFEM). For the rectangular FGM plate with different types of the local crack, Joshi et al [32] gave the theoretical solution of the critical buckling temperature rise.…”

Abstract:The shell with functionally graded material (FGM) coating is a novel high temperature resistant structure, which has been increasingly applied in the aerospace, nuclear, turbo machinery and other engineering fields. However, there are some defects for practical structure due to the limitation of manufacturing technique. But relevant theoretical research on the thermal buckling behavior of the imperfect cylindrical shell is rather limited in most open literature. Therefore, this work proposed to establish the theoretical solution of the critical buckling temperature rise of the cylindrical shell with an axisymmetric imperfect and FGM coating based on the Donnell shell theory, Koiter model and Galerkin method. The result shows that the theoretical solution is in exact agreement with the literature. In addition, the influences of the profile of the axisymmetric imperfection, the volume fraction of the ceramic phase and the types of the thermal loading on the thermal buckling behavior of the imperfect cylindrical shell with FGM coating are analyzed comprehensively. The study provides a scientific solution and better understanding for the thermal buckling problem of the imperfect cylindrical shell with FGM coating.
