The successful predictions are made using strains calculated for an entirely elastic representation of the material, which is possible because of the brittle character of the stress strain curves.
This is the focus of the non-linear homogenization procedure developed in this paper, which is based on the separation of the heterogeneous material system in phases of constant strength properties, a non-linear elastic representation of the limit stress state in each phase, and the definition of appropriate effective strain quantities that capture the morphological features of the microstructure.

For theoretical validation, such methods require a characterisation of the uniaxial stress-strain behaviour of structural steel beyond an idealised elastic-plastic representation.
In this paper, we present a computer model based on an elastic string network representation for sail deformation.
Alonso et al. ([1999]) extended the above model to expansive soils by including a conceptual fabric representation: elastic deformations in microstructure and plastic deformations in macrostructure (Gens and Alonso [1992]).
In this implementation of the DWNM, the free energy function is reduced to an elastic-network model representation near the two reference states.
Besides the numerical representation of elastic properties of elastomers, a thermo-mechanical finite element model to capture strain-induced crystallization (SIC) in elastomers under static and dynamic loading is proposed in this contribution.
Figures 6, 7, and 8 show the most common graphic representation for elastic or storage modulus, the viscous or loss modulus, and tan delta as a function of temperature, respectively.
Such elastic network model (ENM) representation can be readily extended to any level (typically Ca-atoms in proteins and P-atoms in nucleic acids) of coarse-graining by proposing different cutoff distances between individual nodes, and spring constants connecting the nodes in this network can be treated uniformly or nonuniformly.
Here, we propose a method for symmetry representations and elastic redundancy for members of tensegrity structures.
A high fidelity approach for wind turbine aero-elastic simulations including explicit representation of the atmospheric wind turbulence is presented.

Since I tried Ludwig back in 2017, I have been constantly using it in both editing and translation. Ever since, I suggest it to my translators at ProSciEditing.
