These are nonlinear elastic materials for which the slope of the stress-strain curve, (ds/de) e, is the strain dependent elastic modulus, the Tangent modulus. Elastic deformation continues until the ...

The tensile behavior of composites is also different from that of metals in the 'plastic deformation' region of the stress/strain curve. The diagram shows the ... and the fiber's Young's modulus is ...

Elongation and tensile modulus are determined using ... dependence of the parameters of both elastic and plastic. The ...
