Theoretically, dozens of constitutive models have been developed to interpret the stress–strain curve for rubber‐like materials but their applicability on PUEs is still suspicious, which results in the selection of models and the initialization of model parameters need expertise experience. We ...
The stress-strain curve of concrete specimens strengthen with FRP (glass fiber-carbon fiber) in Non-Fire Exposed condition is shown in Figure 5.

In the case of purely linear elastic material, the stress-strain curve reduces to a line, replicating Hooke’s law. On the other hand, if the stress-strain plot deviates from the elliptical geometry into a non-elliptical hysteretic response, it implies that the polymer response trespassed into...
Liliane Bokobza, in Polymer, 2007 The strain–stress measurements were carried out at room temperature on strips of 50 × 5 × 0.2 mm3 between two clamps by means of a sequence of increasing weights attached to the lower clamp. The distance between two marks on the sample was measured with...
The stress-strain curve typically has two parts: the elastic region and the plastic region. In the elastic region, the material deforms in response to the applied stress, but the deformation is not permanent. The material returns to its original shape and size when the stress is removed. The...
The mechanical test is based on the compression of a single bead from which stress-strain data are obtained. Simulations based on the finite element model are used to investigate whether or not an apparent elastic modulus found as the slope of the initial close to linear stress-strain curve ...
The non-linear stress–strain relation for cross-linked polymer networks is studied using molecular dynamics simulations. Previously we demonstrated the importance of trapped entanglements in determining the elastic and relaxational properties of networks. Here, we present new results for the stress versu...
Stress relaxation was measured after application of a double-step shear strain on a concentrated solution of polystyrene in chlorinated biphenyl. The first shear strain s1 was applied to the sample in a cone-plate sample holder of a relaxometer at time
The need for thorough mathematical description of the flow stress curve is increasing, related particularly to its dependence on strain, strain rate, and temperature. This paper explores the potential of an approximate description of the stress-strain relationship. Listed are the principles and the pr...
