Capsizing due to friction-induced twist in the failure of stopper knots

Pedro Miguel Nunes Pereira de Almeida Reis, Paul Johanns

We investigate the failure mechanism of stopper knots, with a particular focus on the figure -8 knot as a representative example. Stopper knots are widely used in climbing, sailing, racket stringing, and sewing to maintain tension in ropes, strings, or thr ...

Effect of fiber architecture on tension-tension fatigue behavior of bolted basalt composite joints

Thomas Keller, Lulu Liu, Xin Wang

The effect of fiber architecture, i.e., unidirectional (UD) vs. multi-directional (MD), on the tension-tension fa-tigue behavior of bolted double-lap basalt composite joints was experimentally investigated. The fatigue load-life (F -N) curves of MD and UD ...

Variational phase-field continuum model uncovers adhesive wear mechanisms in asperity junctions

Jean-François Molinari, Sylvain Collet

Wear is well known for causing material loss in a sliding interface. Available macroscopic approaches are bound to empirical fitting parameters, which range several orders of magnitude. Major advances in tribology have recently been achieved via Molecular ...

Statistical Fatigue Investigation and Failure Prediction of a Healable Composite System

Véronique Michaud, Amaël Maximilien Cohades

Fiber reinforced polymers are massively used as an alternative to metals in structural applications. The brittle nature of their matrix, however, makes them more susceptible to crack formation and propagation resulting in costly repair operations and incre ...

Effect of a second layer on the time to failure of compressed riprap as mountain riverbank protection

Anton Schleiss, Michael Pfister, Mário Jorge Rodrigues Pereira Da Franca, Mona Jafarnejad Chaghooshi

Recently, Jafarnejad, Franca, Pfister, and Schleiss [2017. Time-based failure analysis of compressed riverbank riprap. Journal of Hydraulic Research, 55(2), 224–235. doi: 10.1080/00221686.2016.1212940] presented an experimental study on the stability of co ...

The influence of through-thickness reinforcement geometry and pattern on delamination of fiber-reinforced composites: Part II - Modeling

Véronique Michaud, John Botsis, Georgios Pappas

This article reports modeling techniques and results based on experimental Mode I characterization of a layered woven GFRP material with tufting reinforcement. Standard tuft and loop-less geometries are investigated on three different areal patterns to eva ...

Dynamic behavior of rock during its post failure stage in SHPB tests

Yang Zou, Yang Zhao, Xin Cai

In order to investigate the micro-process and inner mechanism of rock failure under impact loading, the laboratory tests were carried out on an improved split Hopkinson pressure bar (SHPB) system with synchronized measurement devices including a high-speed ...

Bonded sleeve connections for joining tubular GFRP beam to steel member: Numerical investigation with experimental validation

Zhujing Zhang, Yu Bai, Chao Wu

This paper investigates an innovative bonded sleeve connection for joining tubular GFRP and steel members. Experimental results focused on mechanical responses of beam-to-column specimens using bonded sleeve connections and conventional steel angle connect ...

Energy dissipation and recovery in web-flange junctions of pultruded GFRP decks

Thomas Keller, Julia De Castro San Roman Fest, Sonia Yanes Armas

The energy dissipation capacity resulting from progressive cracking and the recovery after unloading of the web-flange junctions (WFJs) of a pultruded GFRP deck were experimentally investigated. Web-cantilever bending experiments up to failure were perform ...
