Aiming to increase damage tolerance of adhesively bonded joints, this work explores the influence CFRP layup adherends on crack onset and propagation composite joints under mode I loading. Quasi-static Double Cantilever Beam tests were performed using four different layups with two adhesives. Parallel experimental program, finite element analyses aid in understanding identifying various mechanisms each specimen type. The results show that adhesive fracture toughness significantly joint...
This paper presents a multiscale hybrid approach for predicting damage and failure of laminated composite structures based on the thermo-mechanical properties (stress/strain behaviour strength) unidirectional plies. kind is thus predictive different stacking sequences. The introduces viscosity matrix in order to obtain an accurate description mesoscopic behaviour, especially non-linearity under shear loading. criterion used physical principles micromechanical aspects (such as effect local...
The aim of this article is to propose a macroscopic damage model, which describes the nonlinear behavior observed on woven composites with ceramic matrix. model built within thermodynamic framework internal variables. First all, efficiency describe mechanical carbon fiber-reinforced matrix outlined. Then, predictive capability evaluated help an alternate torsion test.
Abstract The investigation of fatigue behavior typically involves time‐consuming tests, leading some researchers to explore methodologies based on self‐heating tests reduce the process. For composite materials, conventional approach piecewise linear approximations curve and stress transition between first second regimes is arbitrarily associated with a lifetime equal 10 6 cycles. This paper proposes novel methodology address these simplifications. First, non‐linear viscoelastic model used...
A new micromechanical-based hybrid mesoscopic 3D approach has presented for the prediction of failure under triaxial loadings. The criterion is based on physical principles and introduces micromechanical aspects (such as effect local debonding) at scale. It capable distinguishing between various modes (e.g. fibre tension, compression, in-plane through-thickness interfibre (matrix or fibre/matrix modes). model was successfully implemented to provide predictions envelopes non-linear...
Transverse cracking induced acoustic emission in carbon fiber/epoxy matrix composite laminates is studied both experimentally and numerically. The influence of the type sensor, specimen thickness ply stacking sequence investigated. frequency content corresponding to same damage mechanism differs significantly depending on sensor sequence. However, centroid does not wholly depend except for inner crack a located close enough crack. Outer exhibits signals with low-frequency content, much...
