“…The elastoplastic-damage constitutive model, originated by Hayakawa and Murakami [57], but enhanced by the additional terms related to the multi-kinematic plastic hardening (cf. Voyiadjis and Al-Rub [58]) and the thermal strain, is developed.…”

This is a review paper on some irreversible thermodynamics-based constitutive models capable of capturing complex dissipative physical bahaviour in multifunctional innovative materials. The thermomechanical response of such materials accounts for two basic sources of material nonlinearity, plasticity and damage, which may result in various failure mechanisms. A number of couplings, such as thermo-elastic-damage, elastic-plastic hardening, plastic-damage hardening, thermo-elastic-plastic-damage, etc., are discussed. Various material symmetry classes, including anisotropy, orthotropy, transverse isotropy, are referred to some innovative materials, such as composite materials, functionally graded structures, thermal or wear resistant coatings, etc. Examples of implementation of chosen models for simulation of some initial boundary problems are presented.

“…The second variable β, represents the scalar cumulated damage measurement, and corresponds to the creation of a new surface (crack). The conjugate force k connected with variable βdetermines also the current damage threshold in (41), see also the model [20]. Distinction between the evolution of damage variable β and this for damage effect variable d is due to the effect of hydrostatic stress, see the following equation:…”

The aim of this paper is to present new modelling dedicated to multiaxial high cycle fatigue (HCF), and applied to polycrystalline metals. The model presented is based on the experimental characterization of damage during HCF tests, under pure tension and torsion modes. The origin of this approach is a mesoscopic model considering three plastic behaviour stages (hardening, saturation and softening) The second purpose is to compare the model predictions with experimental data, after identification of the parameter for a ferritic-pearlitic steel. The case of in-phase loading is merely studied here. In particular, the evolution of a few internal variables is discussed and correlated with the available physical features. It is shown that this model provides a complementary insight into a crystal with respect to the endurance criterion of Dang Van. The model predicts, in a particular stress amplitude range, the damage growth arrest.

“…Expressions for M D and L D that appear in formulae for eq (13) and Y eq (16) are based on the assumption that in no-damage state both yield and damage functions are isotropic. It was experimentally proved that for the purpose of modeling spheroidized graphite cast iron the formulae (14) and (17) are justified (cf. [17]).…”

The model of thermo-elasto-plastic damage functionally graded material is developed and the numerical simulation of the material behaviour under complex thermomechanical loading conditions is performed. Sensitivity of the model response to variation of the basic mechanical moduli is examined for a graphite cast iron characterized by a changing volume fraction of graphite particles. The capability of the model to predict response of the complex (thermal barrier/functionally graded material/substrate material) system under thermal loading is checked by the use of two constituents: cast iron and ceramic, and the spatially changing temperature-dependent properties are governed by the appropriate rule of mixture. The response of the threelayer TBC/FGM/S system is compared to the reference metallic structure to show the benefits of the three-layer system.
