The Importance of Safety Engineering in the Design and Assessment of Foundations
Abstract: In safety engineering, ensuring the stability of structures under lateral loads is a critical aspect of foundation design. Lateral forces, such as wind, seismic activity, or other environmental pressures, exert overturning moments on columns, which must be carefully managed to prevent structural failure. To maintain stability, the overturning moment at the foundation base, generated by these lateral loads, must always be less than the restoring moment produced by the soil's …

Viscoelastic Behavior, Interfacial Mechanics, and Reliability of Polymer Interlayers in Laminated Glass Composites: A Comprehensive Review
Abstract: The laminated glass systems are regarded as hybrid polymer–glass composites where the viscoelastic behavior of polymer interlayers mostly controls mechanical response. These interlayers (polyvinyl butyral (PVB), ionoplast, ethylene-vinyl acetate (EVA), etc.) have time-, temperature- and rate-dependent properties which significantly affect shear transfer, energy dissipation, and fracture resistance. But the baseline polymer-relevant processes at the molecular and interfacial level are to a large extent unknown [1]. This review provides a materials-focused …
