Pressed lithium disilicate glass ceramics: Microstructural characterization, in vitro and in silico nonlinear dynamic analysis for biaxial flexural strength

Journal of Prosthodontics, EarlyView.
Abstract Purpose To evaluate the mechanical properties of lithium disilicates, and to assess the predictive capability of in silico models for biaxial flexural strength (BFS). Materials and Methods Specimens of four heat‐pressed lithium disilicates (IPS e.max Press, Rosetta SP, LiSi Press, Vintage Prime Press) were obtained.

Numerical Study of Dynamic Behaviors of Concrete Under Various Strain Rates

Archives of Civil Engineering, 2019
As the dynamic behavior of the concrete is different from that under static load, this research focuses on the study of dynamic responses of concrete by simulating the split Hopkinson pressure bar (SHPB) test.

Denoising Diffusion Model With Pixel‐Adaptive Convolutions for Sheet Metal Forming Analysis

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 2, June 2026.
ABSTRACT Traditional tool development processes in mechanical forming, especially for pressing tools, are often limited by time‐consuming trial‐and‐error cycles, which rely heavily on expert knowledge. These cycles can create bottlenecks and increase costs.

Tissue‐Level Neck Response in Rotary‐Wing Aircrew With Head‐Supported Mass Assessed With Finite Element Model

International Journal for Numerical Methods in Biomedical Engineering, Volume 42, Issue 5, May 2026.
Rotary‐wing aircrew have reported the occurrence of neck pain, potentially associated with rapid scanning tasks and head‐supported mass (HSM). The aim of this study is to gain additional insight into the interaction of HSM and neck positions with the innervated tissues in the neck.
