In loading process of FRP laminates, two kinds of nonlinearity are observed. One of them is concerned with damage, the other is not. The nonlinearity unrelated with damage is mostly due to the nonlinear property of lamina in shear. On the other ha...
In Part I of this study, the constitutive equation of a cracking layer was formulated introducing the new concept that a cracked lamina was replaced by an equivalent uniform work-softening layer. Part II formulates laminate constitutive equation i...
Matrix cracking evolution in composite laminates is formulated in the framework of the continuum damage mechanics. In this paper, the damage evolution of a cracking layer is exclusively focused on. We propose a new concept that a cracked lamina is...

Ultrasonic testing is applied to evaluate cure degree of resin in GFRP laminates. Polymer based composite materials are widely used to repair aged structures in civil engineering because they have high specific strength and good corrosion resistan...
