Diffusion-based Assay:

Article Title: A diffusion-based approach for modelling crack tip behaviour under fatigue-oxidation conditions
Article Snippet: Implementation of the interaction between deformation and diffusion analysis was based on a series of subroutines for FE software ABAQUS [(UMAT (user-defined material subroutine), URDFIL, UMATHT and UEXPAN] used to define and compute constitutive behaviour, the gradient of hydrostatic stress, the mass diffusion process and compositional dilatation.

Article Title: The microstructural evolution and mechanical response of laser direct energy deposition Inconel 718 alloy based on simulation and experimental methods
Article Snippet: During laser directed energy deposition (LDED), the complex microstructure created by multiple rapid heating and cooling cycles results in the uneven performance of the parts.. This work investigates the microstructure evolution and mechanical properties of LDED Inconel 718 samples with different deposit shapes of single-track and thin-wall.. The crystal plasticity constitutive and statistical microstructure modeling combined with experiments were performed to explore the influence of microstructure on tensile property.

Article Title: Snap buckling of NiTi tubes
Article Snippet: They developed a new constitutive model based on J 2 -type non-linear kinematic hardening with the back stress and mplemented it into a user-defined material subroutine (UMAT) n ABAQUS software.

Article Title: Progressive crack growth analysis using interface element based on the virtual crack closure technique
Article Snippet: This paper introduces an interface element to solve 2D progressive crack growth problems under mixed-mode loading.. The interface element is developed to calculate the strain energy release rates based on the virtual crack closure technique (VCCT) in conjunction with finite element analysis (FEA).. A very stiff spring is placed between the node pair at the crack tip to calculate the internal forces.
