Characterization of glass fiber reinforced polymer via digital volume correlation: Quantification of strain activity and damage growth

نویسندگان

چکیده

Strain and damage distributions within a dogbone specimen containing rectangular notch were assessed in-situ via X-ray computed tomography coupled with digital volume correlation. The cut from continuous glass fiber mat reinforced polyester resin composite plate was subjected to cyclic tensile loading. strain–damage interplay evaluated by analyzing major eigen strain correlation residual fields. horizontal strained band emanating the root present beginning of final failure proceeded along this band. first cracks did not initiate in notched region, despite high gradients. activity growth quantified cumulative probabilities strains. comparison made between region remaining part inspected specimen. It is shown that, although mean levels higher standard deviations

Effects of Glass Fiber Reinforced Polymer on Geotechnical Properties of Clayey Soil

Soil reinforcement can be considered as the combination of two parts. One part is soil for compressive stress capacity and another part is some material such as geosynthetics such as steel belts and fibers for tensile stress capacity. Soil improvement is one of the useful methods to increase the strength parameters of the soil. The main goal of this study is to evaluate the effects of GFRP on t...
