In-situ repair of composite sandwich structures using cyanoacrylates

A novel method for the in-situ repair of composite sandwich structures using microvascular networks and cyanoacrylate (CA) adhesive systems has been presented. Upon a damage event, the vascules become ruptured, providing a route for the introduction of adh ...

Influence of visco-elasticity on the stress development induced by alkali-silica reaction

Karen Scrivener, Cyrille Dunant, Alain Benjamin Giorla

The alkali-silica reaction causes long-term degradation in the microstructure of affected concrete as well as macroscopic expansion. In this paper, a micro-mechanical model based upon an explicit representation of the microstructure has been used to simula ...

Dynamic crack propagation in a heterogeneous ceramic microstructure, insights from a cohesive model

Jean-François Molinari, Nicolas Richart, Seyedeh Mohadeseh Taheri Mousavi, Cyprien Wolff

A 2D plane-strain dynamically propagating crack under tensile loading is simulated with cohesive elements. Information of the main crack is extracted from a diffuse crack network with the use of graph properties. Micro-transgranular fracture properties are ...

On measuring fracture toughness under load control in the presence of slow crack growth

Andreas Mortensen, Goran Zagar, Martin Guillermo Mueller, Václav Pejchal, Aparna Singh

The influence of slow crack growth in ceramics on the measurement of their fracture toughness under steadily increasing controlled load (as is generally practiced in microscale testing) is analyzed to identify conditions under which the phenomenon can caus ...

Effect on Bridge Load Effects of Vehicle Transverse In-Lane Position: A Case Study

Mark Anthony Treacy

This paper presents an investigation of the influence of vehicle transverse in-lane position on bridge traffic load effects. To analyze the influence, both finite-element analysis and statistical analysis methods are used, and various technical aspects are ...

Finite Element Analysis for Fatigue Damage Reduction in Metallic Riveted Bridges Using Pre-Stressed CFRP Plates

Alain Nussbaumer, Masoud Motavalli, Gary Scott Prinz, Andrin Herwig, Mario Fontana, Elyas Ghafoori, Emmanuel Mayor

Many old riveted steel bridges remain operational and require retrofit to accommodate ever increasing demands. Complicating retrofit efforts, riveted steel bridges are often considered historical structures where structural modifications that affect the or ...

Fatigue Response of Solvent-Based Self-Healing Smart Materials

Véronique Michaud, Sam Neuser

We investigated the healing of epoxy resins with embedded ethyl phenylacetate (EPA) solvent loaded capsules and shape memory alloy (SMA) wires under fatigue loading in tapered double cantilever beam (TDCB) mode. Under cyclic loading, the kinetics of solven ...

Improving Fatigue Evaluations of Structures Using In-Service Behavior Measurement Data

Ian Smith, James-Alexandre Goulet, Romain Pasquier, Claire Acevedo

Conservative models and code practices are usually employed for fatigue-damage predictions of existing structures. Direct in-service behavior measurements are able to provide more accurate estimations of remaining-fatigue-life predictions. However, these e ...
