“…Note here that 11), with the main difference that here z jm is the dependent variable (because ζ jm does not have meaning without a cutout). Additionally, it should be noted that no logarithmic or negative exponential terms are used in (12), with respect to (11), given that it does not make sense to consider them without a cutout.…”

“…In addition, it is possible to substitute ζ jm = e iψ in (11) or (12), and subsequently the expressions of Φ obtained on the right-hand side of (16). Finally, by grouping terms with the same power of ζ j in (18), a total of 2N + 1 equations are obtained, which reduces the number of unknowns to one half,…”

“…In addition, there have been interesting investigations on this topic with the aim of increasing the application range of the original methodology. For example, Mao 100 and Xu [11] presented a solution for the bending considering multiple cutouts, Hufenbach et al [12] developed a formalism for thick laminates that considers a firstorder shear deformation theory for the laminate bending, Ukadgaonker and Rao [13] introduced hole geome-105 tries other than the elliptical by defining a customised conformal mapping for each geometry, and Ko and Lin [14] defined a methodology to estimate the layerwise 3D full stress tensor from the solution of the 2D membrane model.…”

Mechanical Performance and Failure Mechanism of Thick-walled Composite Connecting Rods Fabricated by Resin Transfer Molding Technique

et al. 2014

A resin transfer molding technique was used to fabricate thick-walled composite connecting rods, and then the mechanical performance of the connecting rod was studied experimentally, at the same time the stress and failure index distributions were simulated numerically. The experimental results show that under a tensile load, the connecting rod first cracks near the vertex of the triangle areas at the two ends, and then the damage propagates along the interface between the main bearing beam and the triangle area as well as along the round angle of the triangle area. Whereas under a compressive load, the delamination primarily occurs at the corner of the U-shaped flange, and the final destruction is caused by the fracture of fibers in the main bearing beam. The simulated results reveal that the tensile failure is originated from the delamination at the round angle transition areas of the T-joints, and the failure strength is determined by the interlaminar strength. Whereas the compressive failure is caused by the fracture of fibers in the main bearing beam, and the failure strength of the structure is determined by the longitudinal compressive strength of the composite material. The simulated results are basically consistent with the experimental results. Hence the mechanical performance and failure mechanism of the complicated composite structure are revealed in great detail through the coupling of the two kinds of research methods, which is helpful for the optimal design of composite structures.
