New method for detecting site liquefaction trigger time based on strong motion records

Yantu gongcheng xuebao
The mechanical properties of soils undergo significant changes before and after liquefaction during an earthquake, which consequently lead to a qualitative shift in surface and structural damage mechanisms.

Linear Mechatronic Modeling of Rectangular Tank Sloshing Dynamics

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Sloshing dynamics in partially filled tanks can strongly influence system‐level behavior when fluid motion couples with rigid‐body dynamics. This paper presents a linear and acausal two‐dimensional sloshing model for rectangular tanks, based on the reformulation of established sloshing theory within a modular, multi‐domain modeling framework ...

Modeling Biocemented Sands: Hypoplastic Model for MICP‐Based Ground Improvement

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Bio‐cementation offers a sustainable and low‐carbon alternative to conventional ground improvement methods, aligning with the growing demand for green geotechnical solutions. To enable reliable numerical simulation of bio‐cemented soil behavior in engineering applications, advanced constitutive models are required to account for the effects of

The Influence of Organic Polymer on Parameters Determining Ability to Liquefaction of Mineral Concentrates [PDF]

TransNav, 2010
When the wet granular materials lose their shear strength they flow like fluids. This phenomenon is called liquefaction. The liquefaction can be prevented by means of limiting the moisture content of cargo by introducing the safety margin. Cargoes, which

Overshooting of Hypoplastic Models With Intergranular Strain: Manifestation, Implications and Remedy

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Intergranular strain extensions of hypoplasticity (IGS, ISA, GIS) are widely used to model small‐strain and cyclic soil behaviour. However, recent studies and our own simulations reveal that these models can exhibit stress overshooting not only under repeated small loading cycles but also during monotonic loading.

Role of Fiber Sizing in Interfacial Relaxation, Water Uptake and Fatigue Properties of Acrylic‐Matrix Composites

Polymer Composites, EarlyView.
Characterisation of glass fibre reinforced acrylic with acrylic‐tailored or multi‐compatible sizing agents. ABSTRACT Fiber‐reinforced infusible acrylic monomer resins are of interest as recyclable alternatives to epoxy and other thermoset resin composites, but the novelty of these resins causes published studies on acrylic‐matrix composites to often ...

Curing Behavior and Structure Reactivity‐Property Relationships in Epoxidized Linseed Oil Thermosets Crosslinked With Biobased Eutectic Hardeners

Journal of Polymer Science, EarlyView.
The curing of epoxidized linseed oil with citric, tartaric, and malic acid–based eutectic hardeners is compared to reveal how acid functionality, hydroxyl content, and molecular geometry govern activation energy, reaction rates, and network rigidity.
