From Shear to Sound: Mechanics–Acoustics Mapping of TPMS Lattices
Advanced Engineering Materials, EarlyView.Triply periodic minimal surface (TPMS) lattices are mapped across mechanical and acoustic performance, revealing that descriptors validated in compression fail under shear. First‐time comparison with trusses included. A transition from porous to resonance‐driven absorption emerges at 25% density.

A Dislocation Perspective on Strength and Toughness in Ceramics
Advanced Engineering Materials, EarlyView.Dislocations in ceramics enjoy a long but yet under‐appreciated history. The three research waves for dislocations in ceramics highlight the topic evolution over the last 90 years. This review focuses on the impact of dislocation on strength and toughness in ceramics.

Exponential decay of shearing stress during jerky flows in a Zr-based bulk metallic glass
AIP Advances, 2013 Presently, an exponential decay of shearing stresses with the time during jerky flows in a Zr-based bulk metallic glass is revealed. The flow stresses with the time satisfy the following equation: σ = A · e−B · x, where A = −158.24*exp ( − N/47.60 ...

Advanced Engineering Materials, EarlyView.This work shows that the mechanical performance of multimaterial digital light processing (DLP) printed thermoset composites is governed by resin compatibility and interfacial design rather than spatial patterning alone. Brittle and ductile resin combinations produced premature interfacial failure, while graded interfaces and mechanically compatible ...

Advanced Engineering Materials, EarlyView.This article presents an experimental and numerical modal investigation of composite sandwich structures using surfboards as model systems. By comparing different core materials and reinforcement strategies, the study demonstrates how local stiffeners influence vibrational response and introduce characteristic modal features, highlighting modal ...

Multi-level analysis of localisation problems
, 2011 Localisation processes, such as shear banding and necking, have been investigated following a macroscopic and a microscopic approach. Both approaches have been formulated within a finite deformation plasticity framework.

2D/3D viscoplastic modelling of shear banding
, 1998 A gradient viscoplasticity model has been used to analyse two- and three-dimensional shear banding. The numerical simulation of a finite width and unique oriention of the shear band is essential.

Shear Banding of Soft Glassy Materials in Large Amplitude Oscillatory Shear [PDF]
, 2016 We study shear banding in soft glassy materials subject to a large amplitude oscillatory shear flow (LAOS). By numerical simulations of the widely used soft glassy rheology model, supplemented by more general physical arguments, we demonstrate strong ...
