Abstract:
... Finite element modeling is an excellent technique for simulating a stitched woven composite to determine its mechanical properties and the analysis of the damage progress. In this technique, actual textile tow geometry measurements based on textile fiber photomicrographs are used to make the internal geometry of the fabric. In this paper, a unit-cell of the stitched composite was generated in micr ...

Tension-Compression and Compression-Compression fatigue tests were carried out on glass/epoxy cross-ply laminates, with different values of the minimum to maximum load ratio R (−1, −3, −5, −7, −10 and 20). During the tests, the damage evolution in the 90° ply was monitored at the macro-and micro-scales. Three damage scenarios were observed, depending on the load ratio: i) initiation and propagatio ...

Abstract:
... Composite tubes have been widely used as the energy absorption device. In order to realize the fine crashworthiness design, it is necessary to perform multiple iteration calculations by the finite element analysis. However, the high-fidelity calculation of the composite damage model is time-consuming (a model with about 320,000 elements requires 32 to 40 h of computation). Therefore, a novel equiv ...

When a glued laminated timber (GLT) beam with a round hole is subjected to a shear force and bending moment, the hole will crack and fail due to a large tensile stress perpendicular to the grain and shear stresses. If the stresses acting on the hole are known, it is possible to estimate the fracture load. However, it is necessary to obtain the stresses acting on the hole by finite element analysis ...
