Axial compression experiments were conducted on pultruded E-glass fiber-reinforced polymer laminates of different slenderness. Second-order deformations greatly increased the bending moments and shear forces of slender specimens. Delamination failure occur ...
The temperature-dependent thermo-physical and mechanical properties of a pultruded E-glass fiber-reinforced polyester (GFRP) composite are investigated in this paper. Fitting of theoretical models of the material properties to results of TGA, DSC, hot disk ...
When structural elements are subjected to compressive loads, the shear forces and stresses induced by second- order effects may lead to shear failure prior to compressive failure. This is particularly likely to occur in the case of pultruded glass fiber-re ...
The direct load transmission behavior of hybrid sandwich beams consisting of a bottom fiber-reinforced polymer skin and a top concrete skin was investigated experimentally. The sandwich core consisted of lightweight concretes of different brittleness (sand ...
This paper presents results of experimental and numerical investigations on double-lap joints composed of pultruded GFRP profiles and polyurethane adhesive subjected to quasi-static axial tensile loading. The objective was to investigate the effect of the ...
A model for predicting composite material strength degradation under elevated and high temperatures is proposed. This model is based on the morphology of the mixture of materials in different states. The degradation of resin-dominated shear strength can be ...
When subjected to elevated and high temperatures, the mechanical properties of FRP composites, such as the E- modulus and viscosity, experience significant changes. At a certain temperature, a composite material can be considered a mixture of materials tha ...
Adhesively bonded joints are being used increasingly in civil engineering structures, especially for joints comprising pultruded glass fiber reinforced polymer (GFRP) laminates. The layered material architecture, however, leads to a complex delamination fa ...
The Weibull distribution, used to describe the scaling of strength of materials, has been verified on a wide range of materials and geometries; however, the quality of the fitting tended to be less good towards the upper tail. Based on a previously develop ...
Genetic programming is used in this paper for modeling the fatigue life of several fiber-reinforced composite material systems. It is shown that if the genetic programming tool is adequately trained, it can produce theoretical predictions that compare favo ...
