Experimental and numerical study on tensile properties of bolted GFRP joints at high and low temperatures

This paper presents both experimental and numerical studies on bolted glass fiber reinforced polymer (GFRP) joints subjected to uniaxial tension different thermal conditions (?20 ?, 20 ? 60 ?). Laboratory tests are conducted obtain strength, elastic modulus deformation of the joints. The model is developed using discrete element method (DEM) that can predict not only above properties joints, but also failure modes with detailed meso/micro damages in consistent observations from tests.
