We study the transverse cracking of the 90◦ ply in [0/90]S cross-ply laminates by means of a discrete element method. To model the 90◦ ply a two-dimensional triangular lattice of springs is constructed where nodes of the lattice model fibers, and springs with random breaking thresholds represent the disordered matrix material in between. The spring-lattice is coupled by interface springs to two...

In this study, the rate dependency of transverse cracking evolution in cross-ply laminates is investigated for several 90° plies thicknesses. The crack detection methodology based on a recently proposed protocol relying use infrared thermography. A new analysis to make it more robust and directly link spatial localization with stress level at which occurs. Based methodology, results obtained va...

A Paper for the World Wise Conference 1999 Winnipeg, Manitoba © November 15, 1999 Introduction Joints are used in concrete pavements in order to control cracking due to thermal and environmental conditions. Dowels span joints to transfer load from one slab to an adjacent slab and to provide vertical and horizontal alignment. Currently, smooth epoxy coated steel dowels are placed across transver...
