Responsive liquid metal materials towards unstructured environment
Responsive Materials, EarlyView.Room‐temperature liquid metals integrate conductivity, deformability, and interfacial dynamics, enabling robust performance in unstructured environments. This review highlights key properties, requirements, and applications across in vivo, underwater, natural, space, and radiation settings, with advances in sensing, actuation, thermal regulation, and ...

Sleep assessment using accelerometry: Not all algorithms are equal
Sleep Research, EarlyView.Abstract Study objectives Accelerometry devices are increasingly used to assess sleep. However, whether different algorithms provide consistent estimates remains uncertain. This study compared sleep parameters derived from two accelerometry‐based algorithms and a self‐reported sleep journal.

steel research international, EarlyView.In this study, the susceptibility to copper‐induced hot shortness of the alloy 42CrMo4 is investigated by different hot tensile tests, as well as by a detailed analysis of the formed oxidation products. While an enrichment of metallic copper and a penetration of the grain boundaries are observed, no critical reduction of the tensile test properties can

Strip loading in reinforced concrete: Mechanical modeling and experimental validation
Structural Concrete, EarlyView.Abstract Strip loading of reinforced concrete is a common problem in engineering practice. The concrete compressive strength at the load introduction can be several times higher than the uniaxial concrete compressive strength, which can be attributed to geometrical and passive confining stresses caused by load dispersion and reinforcement, respectively.

A new smooth failure criterion for concrete inspired by Lubliner's condition
Structural Concrete, EarlyView.Abstract A new failure criterion with 10 parameters is proposed, based on Lubliner's idea of joining two Drucker–Prager cones. The novelty lies in the way of introducing deviatoric shape variation: through two Podgórski's functions. This feature allows for improving plane stress cross‐section's compatibility with experimental data.

Strip loading in steel fiber reinforced concrete: Experimental and theoretical investigation
Structural Concrete, EarlyView.Abstract Fiber reinforced concrete is becoming increasingly popular in engineering practice due to its high robustness, post‐cracking behavior, and crack control. For strip loading, as common, for example, in longitudinal joints of tunnel lining segments, the use of fiber reinforced concrete has the potential to reduce conventional reinforcement ...
