Simulation of instabilities in non-softening Drucker-Prager plasticity
Computer Assisted Methods in Engineering and Science, 2023 The problem of instability and strain localization in a hardening non-associative Drucker-Prager plasticity theory is analyzed. The classical and gradient-enhanced versions of the theory are reviewed and instability indicators are summarized.

Advanced Materials Technologies, EarlyView.Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...

Simulation of hydro-formability testing for tubes [PDF]
, 2004 With the development of dedicated tubular products for hydroforming, the need for a representative\ud test for these products evolves. Currently free expansion tests are used, but these tests only follow a more\ud or less plane strain deformation.

Dynamic Current Routing in Conductive Liquid Crystal Elastomers for Complex Deformation Actuators
Advanced Materials Technologies, EarlyView.This work introduces a novel actuation control strategy in which electrical stimulation generates localized Joule heating in conductive liquid crystal elastomer (LCE) surfaces, enabling complex 3D deformations from a single homogeneous surface without preprogramming.

Influence of section depth on the structural behaviour of reinforced concrete continuous deep beams [PDF]
, 2007 YesAlthough the depth of reinforced concrete deep beams is much higher than that of slender beams, extensive existing tests on deep beams have focused on simply supported beams with a scaled depth below 600 mm.

Advanced Optical Materials, EarlyView.A dual‐domain PSLC architecture enables direct comparison of alignment‐dependent laser damage within a single device. Crack‐like and seal‐like morphologies emerge under different damage conditions, and their evolution is interpreted through quantitative image analysis and heat‐driven simulations.
