Mathematical Methods in the Applied Sciences, EarlyView.ABSTRACT A class of one‐dimensional impact and dynamic contact problems taking into account non‐smooth velocities is studied. The new space‐time finite element approximation of dynamic variational inequalities is suggested. The non‐smooth solution for the impact of an obstacle by an elastic bar and its energy conservation under persistency conditions ...

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.ABSTRACT Localized deformation in dense granular materials, often culminating in the formation of shear bands, is a key failure mechanism in geotechnical and material systems. However, predicting the onset of such localization remains a fundamental challenge due to the system's inherent inelasticity and microstructural complexity.

People and Nature, EarlyView.Abstract Community‐led restoration operates at the intersection of ecological feasibility and social acceptability. In the marine realm, restoration is challenging due to gaps in ecological knowledge on how and where to restore lost ecosystems and limited public engagement that provides social licence for restoration.

On the Damage Tolerance of Diffusion Bonded Titanium–Aluminum Phase Biomimetic Composites
Rare Metals, EarlyView.ABSTRACT The biomimetic design principles of natural structures involve the strategic integration of stiff and compliant phases to synergistically enhance strength and toughness. Its evolutionary refined natural armor, characterized by a specialized microarchitecture, enables superior damage tolerance.
