Physically based finite element strength prediction in notched woven laminates under quasi-static loading
The present paper is concerned with modelling damage and fracture in notched woven fabric composites. Previous experimental work has shown that, under tensile loading, damage at a notch in a variety of glass fibre reinforced plastic (GFRP) and carbon fibre reinforced plastic (CFRP) composites based...

| தொகà¯à®ªà¯à®ªà¯: | The present paper is concerned with modelling damage and fracture in notched woven fabric
composites. Previous experimental work has shown that, under tensile loading, damage at a
notch in a variety of glass fibre reinforced plastic (GFRP) and carbon fibre reinforced plastic
(CFRP) composites based on woven fabric reinforcement comprises matrix damage and fibre tow
fracture along the plane of maximum stress. It is these experimental observations that inform the
failure modelling developed here, in which a cohesive zone approach is used within a twodimensional
extended finite element method framework. The traction–separation parameters
used in the extended finite element method implementation are based on previously reported
experimental measurements for the strength and toughness of the woven fabric materials under
investigation. The approach is shown to provide predictions of notched strength that are in very
good agreement with experimental results from the literature for a range of glass fibre reinforced
plastic and carbon fibre reinforced plastic woven fabric systems and also agree well with results
obtained from closed form analytical models, which require calibration |
