Crystallographic texture dependent bulk anisotropic elastic response of additively manufactured Ti6Al4V (open access)

Crystallographic texture dependent bulk anisotropic elastic response of additively manufactured Ti6Al4V

This article identifies a bulk texture effect on elastic anisotropy in laser powder bed fused Ti6Al4V by employing an effective bulk modulus elastography technique coupled with ultrasound shear wave velocity measurement at a frequency of 20 MHz inside the material.

Characterize traction–separation relation and interfacial imperfections by data-driven machine learning models (open access)

Characterize traction–separation relation and interfacial imperfections by data-driven machine learning models

This article combines machine learning (ML), finite element analysis (FEA), and empirical experiments to develop data-driven models that characterize interfacial mechanical properties precisely. It also provides a code package containing trained ML models, allowing other researchers to establish T–S relations for different material interfaces.
