Article

Designs of grips for flat strips made of fiber-reinforced polymers (FRPs) are put forward. They can be used for tests in tension, prestretching, and long-term loading. In order to prevent the rise of stress concentrations, special profiled grips with a varying surface curvature allowing the transmission of tensile loads to the strip by means of gradually increasing shear stresses (without peaks) have been elaborated. The results of a mathematical analysis of the stress state in the strip, an example of calculation, and experimental data obtained from testing a carbon-fiber-reinforced polymer strip in profiled model grips specially constructed for this purpose are presented.
