The present study aims to investigate the interaction of ratcheting and fatigue phenomena for additively manufactured (AM) samples SS304L AlSi10Mg undergoing uniaxial asymmetric stress cycles. Overall damage was accumulated through on AM prepared from three-dimensional-printed plates along vertical horizontal directions. Fatigue evaluated based strain energy density approach calculated use an i...

Abstract In this study, a new method for determining the material parameters of cyclic plasticity is presented. The can be applied to evaluate model from any loading histories measured experimentally. experimental data require basic processing only utilized. calibrate different elastoplastic models such as Chaboche–Rousselier (Ch–R) constitutive equation or other formulations which use rules is...

Constitutive modeling of material behaviour is becoming increasingly important in prediction of possible failures in highly loaded engineering components, and consequently, optimization of their design. Damage occurrence and accumulation within the material are described in this paper by means of models of kinematic and isotropic hardening according to Chaboche material model. Since the materia...

Two parameters are identified for characterizing the deformation in the plastic zone near the tip of a crack when mixed mode conditions prevail. Details of the near-tip stress and strain distributions are presented f or hardening materials in which a diffus e plastic zone occurs under plane stress conditions. For small scale yielding the two near-tip parameters are related to the two elastic s ...

The evolution of plastic deformation and damage in steel frame buildings caused by seismic action is simulated based on a modified damage model. This model combines nonlinear isotropic and kinematic hardening criteria with a damage evolution law expressed in terms of plastic displacement. A nine-story steel frame is chosen as a reference structure, and a nonlinear damage analysis is performed u...

Abstract In this work the finite element (FE) implementation of small strain cyclic plasticity is discussed. The family elastoplastic constitutive models considered which uses mixed, kinematic-isotropic hardening rule. It assumed that kinematic governed by Armstrong–Frederick law. radial return mapping algorithm utilized to discretize general form equation. A relation for consistent tangent ope...

Sn-Pb eutectic solder alloy is extensively used in microelectronics packaging interconnects. Due to the high homologous temperature, eutectic Sn-Pb solder exhibits creepfatigue interaction and significant time-, temperature-, stress-, and rate-dependent material characteristics. The microstructure is often unstable, having significant effects on the flow behavior of solder joints at high homolo...
