Anisotropic Initial Damage and Its Effect on Tensile Response of Plain Concrete
ABSTRACT Damage is often described as isotropic, implying that a scalar value describes its initial state. However, the prior micro‐cracking pattern at points of an existing building, that is, the initial damage, may be oriented by a preload. The degradation of the Volume Element due to oriented preloads shall be described as anisotropic and ...

ABSTRACT Background Conventional laparoscopic instruments provide limited dexterity in confined anatomical environments, whereas existing articulated designs rely on complex rigid joints or motorised actuation, increasing mechanical complexity and limiting miniaturisation.

Uncovering hidden bias in neutron diffraction residual strain measurements
This work demonstrates that diffraction‐based residual strain calculations and uncertainty estimates depend on how grain populations are sub‐sampled, with important implications for interpreting residual stresses in heterogeneous materials with fine‐scale microstructure and strain gradients.When calculating residual strain via neutron or X‐ray ...

Toughening of TiO2 via Femtosecond Laser Shock Peening
ABSTRACT Most ceramics have low fracture toughness (<5 MPa m$\sqrt{m}$) at room temperature. This work explores the feasibility of toughening TiO2 via femtosecond laser shock peening (fs‐LSP). Transmission electron microscopy (TEM) analyses reveal LSP‐induced the creation of high‐density stacking faults, dislocation structures, and twin boundaries in ...

A new methodology shows that current multiaxiall fatigue criteria are not sufficient. ABSTRACT In the present work, mappings of two invariants of the true strain tensor, K2$$ {K}_2 $$ that measures the magnitude of the distortion and K3$$ {K}_3 $$ that quantifies the mode of distortion, are used to investigate the multiaxial fatigue of AE2 and AE42 ...
