Fatigue &Fracture of Engineering Materials &Structures, Volume 46, Issue 10, Page 3872-3891, October 2023., 2023 Abstract In this study, the fatigue crack growth rate in four different tool steel microstructures (hot rolled, powdermetallurgically processed, as‐cast, and carbide‐free) is experimentally measured and correlated with hard phase size and spacing, as well as with the roughness of the fracture surface that is created by crack kinking.

Material Testing 2.0: A brief review
Strain, Volume 59, Issue 3, June 2023., 2023 Abstract With the advent of camera‐based full‐field measurement techniques such as digital image correlation (DIC), researchers have been trying to exploit such rich data sets through the use of more complex test configurations than the standard ones (uniaxial tension/compression, bending etc.).

Decompression and Fracturing Caused by Magmatically Induced Thermal Stresses
Journal of Geophysical Research: Solid Earth, Volume 128, Issue 3, March 2023., 2023 Abstract Studies of host rock deformation around magmatic intrusions usually focus on the development of stresses directly related to the intrusion process. This is done either by considering an inflating region that represents the intruding body, or by considering multiphase deformation.

An EVP Double‐Yield Nonstationary Flow Surface Model for Soft Clay
Advances in Civil Engineering, Volume 2022, Issue 1, 2022., 2022 According to experimental findings, soft clay has compression and shear creep. The goal of the study is to develop an elastic‐viscoplastic (EVP) model for the viscous behavior of soft clay. The new EVP model is deduced from the associated flow rule, Yin’s double‐yield surface theory, and the critical state soil mechanics. The nonstationary flow surface

Analysis of Damage Constitutive Model for Frozen Red Clay under Uniaxial Compression
Advances in Materials Science and Engineering, Volume 2022, Issue 1, 2022., 2022 At present, it is in the peak period of infrastructure construction in western China, and due to the natural climate, the soil has been frozen for a long time, but there is little research on frozen red clay at present. Therefore, it is necessary to further study the mechanical properties of frozen red clay.

GAMM-Mitteilungen, Volume 44, Issue 3, September 2021., 2021 Abstract When developing reliable and useful models for selective laser melting processes of large parts, various simplifications are necessary to achieve computationally efficient simulations. Due to the complex processes taking place during the manufacturing of such parts, especially the material and heat source models influence the simulation ...

An anisotropic viscoplasticity model for shale based on layered microstructure homogenization
International Journal for Numerical and Analytical Methods in Geomechanics, Volume 45, Issue 4, Page 502-520, March 2021., 2021 Abstract Viscoplastic deformation of shale is frequently observed in many subsurface applications. Many studies have suggested that this viscoplastic behavior is anisotropic—specifically, transversely isotropic—and closely linked to the layered composite structure at the microscale.

Non-local fractional model of rate independent plasticity [PDF]
, 2013 In the paper the generalisation of classical rate independent plasticity using fractional calculus is presented. This new formulation is non-local due to properties of applied fractional differential operator during definition of kinematics.

On stress resultant plasticity and viscoplasticity for metal plates [PDF]
, 2008 In this work we derive elastoplastic and elastoviscoplastic finite element formulations for stress resultant bending analysis of thin metal plates. The principle of maximum plastic dissipation is used to obtain the ingredients of the small strain stress ...

Model for (De)Compaction and Porosity Waves in Porous Rocks Under Shear Stresses
Journal of Geophysical Research: Solid Earth, Volume 125, Issue 8, August 2020., 2020 Abstract An understanding of instantaneous and long‐term compaction of porous rocks is important for reservoir engineering and Earth sciences. Experience from laboratory triaxial compression tests and from subsurface operations indicates that shear and volumetric deformations are interdependent.
