The infinitesimal strain tensor is a symmetric tensor characterised by nine components that in three-dimensional rectangular Cartesian coordinates reads:εij=[εxxεxyεxzεyxεyyεyzεzxεzyεzz]where the diagonal components εkk [-] are called normal strains and represent stretching of an element...

A work-around I tried was to simply make my own strain rate tensor, E, using a symmetric tensor field function. The formula is E = 1/2 (∇V + ∇V^T), where ∇V is the divergent of the velocity vector and ∇V^T is its transpose. The problem I then ran into is that I...

the convolution in time, gkj,p(x,t:ξ,τ) is the spatial derivative of the Green’s function which describes the displacement in the k direction at point x and time t due to a unit impulsive force at location ξ in the direction j at time τ, and mjp is the moment tensor (MT96)...
Three Gaussian process regression-based surrogate models are trained (one per stress component) between principal invariants of strain and strain rate tensors and the corresponding coefficients of the integrity basis components. It is demonstrated that this type of model construction enforces key physics...
The material time rate of Lagrangean strain measures, objective corotational rates of Eulerian strain measures and their defining spin tensors are investig
the existence of an elastic strain energy function can be assumed such that a linear relation can be used between the Cauchy stress tensor σ and the engineering elastic strain tensorε'. The engineering elastic strain tensor ε' can be considered here instead of the elastic strain tensor due ...
In a strain-driven process, the total strain tensor is regarded as an independent variable (generally known), and the evolution of the viscoplastic strain rate tensor is defined by the viscoplastic flow rule such that (9.71)ε̇ijvp=λ̇vp∂f∂σij=λ̇vpNij where Nij is the unit...
