The material model was further tested for stability under different strain rates and then held under constant state of strain
to evaluate stress redistribution over time using simple tension tests and compression tests as shown in Figure 15.
The tensor of the state of strain in the matrix form is presented in the following way (Lebedev, 2010):
2013; Talich, 2007; Cai, 2001) confirm that the constructions called rosettes are successfully applied to determine the state of strains in large areas (rosette sides of lengths of several dozen kilometres), as well as locally (sides about 20 metres).
Assuming the complete recoverability after deformation, the strain energy density depends only on the final state of strain
and in no way on the loading history.
The two-dimensional (2D) model with a crack was formed with the help of programmable system ANSYS, because, it allows to show plane state of stress and plane state of strain in the model (Fig.
When using the plane model, opening of the crack contour was obtained in two cases: plane state of stresses and plain state of strains.
Grinding thus becomes dependent on the internal state of strain
of the particles.
g], at which temperature, different stress would be obtained according to the specimen state of strain
In this work, a constitutive model, developed previously , leads to the evaluation of the rate of plastic deformation in glassy polymers, based on the distribution of plastic shear transformations in a completely different way: What is distributed is the strain, and, in respect to the overall state of strain
, the fraction of sites that have been plastically transformed can be calculated.
