The components of stress, strain, displacement, electric field, electric displacement, and electric potential will all be given in terms of these three potentials.
The paper presents a method of identification and calculation of the components of strain energy density under cyclic and random loading causing elastic plastic strain in the material.
The elastic and inelastic components of strain energy release rate are separated in an effort to capture the fundamental toughening mechanisms in these systems.
In the austenite matrix surrounding thin plate martensite, the magnitude of components of strain tensor is nearly as large as those of rotation tensor, implying that shape strain of thin plate martensite is accommodated by elastic deformation of austenite.
On the other hand, in the austenite matrices surrounding lenticular and lath martensite, components of strain tensor are found to be much smaller than those of rotation tensor even near the austenite/martensite interface.
The displacements field of this element is based on the assumed functions for the various components of strain which satisfy the compatibility equation and it is developed in some way to improve the element performance in the distorted configurations.
This study presents a finite element (FE) model capable of predicting the final residual stress field in an inertia friction welded component of a CrMoV steel considering the elastic and inelastic components of strain resulting from mechanical deformation, temperature changes in the material and volumetric changes associated with phase transformations.
After a global balance analysis versus frequency, a local study has been carried out in order to quantify the relative contribution of the components of strain and stress tensors to the total strain energy and dissipated power; the individual layer's contributions is also investigated.
The total strain and strain rate can be decomposed into elastic, plastic, creep and thermal components of strain and strain rate.
