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

open access: yesnpj 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

open access: yesMaterials 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.

Methodology for Determining the Compliance Matrix and Analyzing the Skew Anisotropic Plate with an Arbitrarily Shaped Hole

open access: yesAdvances in Materials Science and Engineering, 2022
The previous analytical methods mainly focused on the analysis of orthotropic, transversely isotropic, or even isotropic materials, and little analyses have been conducted on nonorthogonal and extreme anisotropic material properties.
