Abstract In this work, the phase-field approach to fracture is extended model fatigue failure in high- and low-cycle regime. The energy degradation due repeated externally applied loads introduced as a function of local accumulation variable, which takes structural loading history into account. To end, novel definition variable proposed, allowing analysis at monotonic without interference exten...

In this paper, we present two new primitives to Aspect-Oriented Programming (AOP) languages that are needed for systematic hardening of security concerns. These primitives are called exportParameter and importParameter and are used to pass parameters between two pointcuts. They allow to analyze a program’s call graph in order to determine how to change function signatures for the passing of par...

In classical mechanical testing, determining the stress and strain states of complex shape specimens turns out to be very challenging, especially in most deformed regions. latter case, when not enough material is present, non-destructive testing needed for corresponding state. this study, a novel approach, based on local quasi-non-destructive instrumented indentation technique (IIT) coupled wit...

Push-pull tests at fixed plastic strain amplitude or stress were run on a TWIP steel, and followed by TEM observations, to analyze its cyclic behavior in relation with the deformation mechanisms. The kinematic isotropic components of flow measured throughout whole hardening/softening stages, their evolution cumulated was compared those tension. rise internal found responsible for initial harden...

This paper is concerned with investigation of vertical impedance function of a surface rigid circular foundation resting on a semi-infinite transversely isotropic alluvium. To this end, the equations of motion in cylindrical coordinate system, which because of axissymmetry are two coupled equations, are converted into one partial differential equation using a method of potential function. The g...

This paper studies the plane constrained shear problem for single crystals having one active slip system and subjected to loading in both directions within small strain thermodynamic dislocation theory proposed by Le (J Mech Phys Solids 111:157–169, 2018). The numerical solution of boundary value shows combined isotropic kinematic work hardening, sensitivity stress–strain curves temperature rat...

The dynamic problem of thermo-elastic-viscous-plastic deformation shallow composite shells is formulated using the refined theory bending. In this case, tangential displacements along thickness constructions are approximated by polynomials third and higher orders, deflection does not depend on transverse coordinate. Normal stresses in composition have a linear distribution over thickness. tempe...

In this paper, an adaptive anisotropic constitutive model, namely AA1-CLAY, is developed for clays based on the critical state framework. The model has a non-associated flow rule, and it can also reduce to basic models. A versatile yield surface (YS) implemented in which generate broad range of shapes improve possibility capturing experimental points different clay types with high accuracy. add...

An efficient numerical integration scheme is proposed for the uniaxial loading of two-layer viscoplastic (TLVP) model, which a built-in material model in commercial finite element software Abaqus. The particular version TLVP under investigation governed by linear isotropic plastic hardening rule with time-hardening nonlinear creep law. new can be easily implemented any programming environment l...
