Elastoplastic compression constitutive behaviours and damage mechanisms of 3D4D braided FRP at temperatures of 25 °C and 85 °C
Distinct plastic plateau and nonlinear elastoplastic constitutive behaviours are substantiated in longitudinal and transverse compression tests on 3D4D braided fibre-reinforced polymer (FRP) at temperatures of 25 °C and 85 °C. A new nonlinear constitutive law is derived to depict elastoplastic compression constitutive...
