Thermal Disturbances in Twinned Orthotropic Thermoelastic Material

open access: yesInternational Journal of Applied Mechanics and Engineering, 2018
This paper deals with deformation in homogeneous, thermally conducting, single-crystal orthotropic twins, bounded symmetrically along a plane containing only one common crystallographic axis. The Fourier transforms technique is applied to basic equations

The importance of intervertebral disc material model on the prediction of mechanical function of the cervical spine

open access: yesBMC Musculoskeletal Disorders, 2021
Background Linear elastic, hyperelastic, and multiphasic material constitutive models are frequently used for spinal intervertebral disc simulations. While the characteristics of each model are known, their effect on spine mechanical response requires a ...
