Anisotropic ductile fracture: experiments, modeling, and numerical simulations

Journal of Materials Research and Technology, 2022
The continuous hot rolling process induces anisotropy in the plastic yield and flow and results in an anisotropic ductile fracture. In this study, experiments, including uniaxial in-plane tension tests and shear tests of butterfly specimens along ...

Naturally occurring van der Waals heterostructure lengenbachite with strong in-plane structural and optical anisotropy

npj 2D Materials and Applications, 2021
Lengenbachite is a naturally occurring layered mineral formed with alternating stacks of two constituent PbS-like and M2S3-like two-dimensional (2D) material layers due to the phase segregation process during the formation.

Remarks on orthotropic elastic models applied to wood

Materials Research, 2006
Wood is generally considered an anisotropic material. In terms of engineering elastic models, wood is usually treated as an orthotropic material. This paper presents an analysis of two principal anisotropic elastic models that are usually applied to wood.
