The non-linear behavior of aqueous model ice in downward flexure [PDF]
arXiv, 2019 As aqueous model ice is used extensively in ice tanks tests on the performance of ship hulls in sheet ice, it is imperative that such model ice replicate the main flexural strength behavior of sheets of sea ice and freshwater ice. Ice tanks use various types of aqueous model ice types, each of which contain brine dopants to scale-reduce ice-sheet ...

Advanced Materials Technologies, EarlyView.This study investigates how laser‐micromachined patterns enhance the interfacial and mechanical properties of bioinspired ceramic composites. The ±45° micro‐pattern significantly improved interfacial bonding and damage dissipation energy by 107%, while integrating micro‐ and macro‐designs increased energy absorption by 60%.

Earthquake Engineering &Structural Dynamics, Volume 52, Issue 1, Page 164-182, January 2023., 2023 Abstract The seismic performance of integral abutment bridges (IABs) is affected by the interaction with the surrounding soil, and specifically by the development of interaction forces in the embankment‐abutment and soil‐piles systems. In principle, these effects could be evaluated by means of highly demanding numerical computations that, however, can ...

Flexural Fatigue Strength of Plain Concrete
ACI Materials Journal, 1993 This paper presents a new expression to describe the flexural fatigue strength of plain concrete. It incorporates the effects of stress ratio and stress level into the faitgue equation and allows a statistical description of fatigue life in terms of both stress level and stress ratio. A concept of equivalent fatigue life is introduced in the derivation

Artificially Weaved Textile‐like Surface Micromachined Graphene‐Polymer Flexible Bioelectrodes
Advanced Materials Technologies, EarlyView.This study reports on the engineering of microscale textured surfaces of SU‐8/PMMA polymer composites much like a “weft‐warp” pattern to resemble “artificially‐weaved” textiles. These microstructured surfaces enable conformal layering of functional reduced graphene oxide (rGO), all‐in‐all offering favorable features including remarkable self ...

Earthquake Engineering &Structural Dynamics, Volume 52, Issue 2, Page 308-334, February 2023., 2023 Abstract Unreinforced masonry (URM) buildings are highly vulnerable to seismic ground motion, calling for quantitative risk assessment and mitigation programmes in different earthquake‐prone countries to reduce future losses. Despite the effectiveness of base isolation technology in reducing seismic response of buildings, the high costs of conventional

A high temperature W$_2$B cermet for compact neutron shielding [PDF]
, 2019 We have developed a new material for neutron shielding applications where space is restricted. W$_2$B is an excellent attenuator of neutrons and gamma-rays, due to the combined gamma attenuation of W and neutron absorption of B. However, its low fracture toughness (~3.5 MPa$\cdot$m$^{0.5}$) and high melting point (2670 {\deg}C) prevent the fabrication ...

Advanced Sustainable Systems, EarlyView.Rigid, lightweight foams for thermal insulation are produced using a universal and scalable method: results are compared between pilot plant trials, four wood residues, pulp, ocean water, and a biosurfactant. Two guidelines for using this method are suggested: use a distribution of rigid wood microparticle sizes and shapes and match the average ...
