Propagation of Matrix Cracking and Induced Delaminatin in Cross-Ply Composite Beams Subjected to Bending Loads
Due to the mismatch of mechanical properties in composite laminates, propagation of delami-nation is considered as a severe damage mechanism in beams with various lay-up configurations. Delamination can be generated due to matrix cracking propagation or it can also be initiated due to the manufacturing process before using composite beams. Using a micromechanics model, this study is aimed to in...
متن کاملBending Response of Cross-Ply Laminated Composite Plates with Diagonally Perturbed Localized Interfacial Degeneration
A laminated composite plate element with an interface description is developed using the finite element approach to investigate the bending performance of two-layer cross-ply laminated composite plates in presence of a diagonally perturbed localized interfacial degeneration between laminae. The stiffness of the laminate is expressed through the assembly of the stiffnesses of lamina sub-elements...
متن کاملOn Bending Tests of Five - Ply
K-factor has Ions been used as a modifier of section modulus In the calculation of bending moment for plywood beams. No comparable modification of moment ot inertia is included In current reoommendatioDS for calculating plywood deflection at span-depth ratios of 30: 1 or greater. Results of limited testing lend support 'to the authors' contention that, where "shear" strains are signifIcant, the...
متن کاملInterlaminar fatigue crack growth of cross-ply composites under thermal cycles
The fatigue growth of a fiber reinforced composite laminate was characterized under thermal cycling using a combined experimental and computational investigation. Twenty-four ply composite laminates (1⁄20 12=90 12 ) are fabricated with a pre-existing delamination, and subjected to thermal cycling in an environmental chamber. The large mismatch in the coefficients of thermal expansion is used to...
متن کاملThe Formation and Effect of Outer-Ply Microcracks in Cross-Ply Laminates: A Variational Approach
The microcracking process in laminates which have outer-ply 90◦ plies (e.g. [90m/0n]s) has some important differences from the microcracking process in laminates which lack outer-ply 90◦ plies (e.g. [0n/90m]s). Foremost among the differences is the characteristic damage state. [90m/0n]s laminates form antisymmetric or staggered microcracks while [0n/90m]s laminates form symmetric microcracks. T...
