A novel approach for tetrahedral-element-based finite element simulations of anisotropic hyperelastic intervertebral disc behavior

Autor: Marie-Rosa Fasser, Ramachandra Kuravi, Marian Bulla, Jess G. Snedeker, Mazda Farshad, Jonas Widmer

Publikováno v: Frontiers in Bioengineering and Biotechnology, Vol 10 (2022)

Intervertebral discs are microstructurally complex spinal tissues that add greatly to the flexibility and mechanical strength of the human spine. Attempting to provide an adjustable basis for capturing a wide range of mechanical characteristics and t

Modified Monte Carlo approach for simulation of grain growth and Ostwald ripening in two-phase Zn–22Al alloy

Autor: Hossein Mohammadi, Ali Reza Eivani, Seyed Hossein Seyedein, Manojit Ghosh

Publikováno v: Journal of Materials Research and Technology, Vol 9, Iss 5, Pp 9620-9631 (2020)

Monte Carlo (MC) simulation was used to predict the microstructural evolution and the kinetics of grain growth during heating of Zn–22Al dual phase alloy. As the prediction of MC simulation is based on virtual simulation time, time conversion plays

Autor: Nishant Mistry, Leonhard Hitzler, Abhishek Biswas, Christian Krempaszky, Ewald Werner

Publikováno v: Mistry, N, Hitzler, L, Biswas, A, Krempaszky, C & Werner, E 2023, ' Predicting anisotropic behavior of textured PBF-LB materials via microstructural modeling ', Continuum Mechanics and Thermodynamics, vol. 35, no. 3, pp. 1185-1202 . https://doi.org/10.1007/s00161-023-01215-x

It is well established that large temperature gradients cause strong textures in as-built metal parts manufactured via laser beam powder bed fusion. Columnar grains with a preferred crystallographic orientation dominate the microstructure of such mat
