Microscopic Stress Analysis of Silicon Carbide Devices Under Overcurrent Conditions in DC Solid‐State Circuit Breakers

IET Smart Energy Systems, EarlyView.
A coupled Saber–TCAD–thermo‐mechanical simulation framework is proposed to evaluate microscopic stresses in SiC MOSFETs under overcurrent operation. Ultrahigh gate‐voltage driving reduces thermal and mechanical stress but increases gate oxide electric‐field stress, revealing a reliability tradeoff for DC solid‐state circuit breakers.

Axial and Biaxial Fatigue Behavior of 6061‐T651 Cold Metal Transfer Welded Joints

Fatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT Lightweight aluminum structures in transportation systems are increasingly exposed to complex service loading, yet the fatigue performance of welded joints is still predominantly assessed using uniaxial data. In this work, the axial and biaxial fatigue behavior of 6061‐T651 aluminum alloy joints produced by cold metal transfer (CMT) welding is

Effect of sintering cycle on the strength and translucency of multilayered zirconia

Journal of Prosthodontics, EarlyView.
Abstract Purpose A newly introduced sintering protocol promises to offer higher translucency while not significantly compromising the flexural strength of the material. However, the effect of the novel sintering protocol has not been thoroughly validated.

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.

A Data‐Based Adaptive Elastic Framework for High‐Accuracy Simulation of Textile Membrane Structures

ce/papers, Volume 9, Issue 4-5, Page 21-26, October 2026.
Abstract In the structural analysis of tensile membrane structures, the linear elastic material model is a widely used tool in engineering practice, owing to its simplicity and low computational cost. However, its inability to accurately represent the strongly nonlinear and anisotropic response of technical fabrics often results in insufficient ...

Background to modification factors in structural membrane design

ce/papers, Volume 9, Issue 4-5, Page 117-121, October 2026.
Abstract The novel European design standard for membrane structures DIN CEN/TS 19102 was published in 2024. Besides others, it provides rules for the stress verification of structural membranes – technical textiles and foils – in the ultimate limit state.

Improving fatigue resistance of translucent 4Y‐PSZ zirconia through glass gradation

European Journal of Oral Sciences, Volume 134, Issue 5, October 2026.
Abstract To evaluate the effect of graded glass infiltration on the fatigue behavior and mechanical reliability of translucent 4Y‐PSZ zirconia before and after hydrothermal aging, disc‐shaped specimens were fabricated by uniaxial pressing and divided into control and glass‐graded groups (n = 36/group).
