The applicability and limitation of several quadratic strength theories were investigated with respect to 2D-C/SiC and 2.5D-C/SiC composites. A kind of damage-b
Under an applied voltage, dielectric elastomers(DEs) produce an actuation strain that is nonlinear, partly because of the material properties. In this study, an
