TL;DR: In this paper, the authors present the shear stress-shear strain behavior of FM73 at elevated temperatures (i.e. 60°C) and show that this time-dependent behaviour can be modelled using the unified constitutive relationship.
33 citations
TL;DR: In this paper, the authors present a design methodology and associated data base for the damage-tolerant design of adhesively bonded repairs, illustrated by repairs to an edge-cracked panel and to multi-site damage in a fuselage lap joint.
29 citations
TL;DR: In this article, the ability of a bonded-composite doubler to restore the fatigue performance of lap-joints containing multi-site damage was investigated and two doublers were applied to representative multisite damage.
19 citations
TL;DR: In this article, it was shown that for composites there is little interaction between damaged regions, provided they are separated by more than one diameter, and this methodology was verified via a coupon test program and an experimental evaluation of two damaged F/A-18 horizontal stabilators.
16 citations
TL;DR: In this paper, a load-bearing hole containing a single "through-thickness" crack was repaired with bonded boron/epoxy doublers and a steel sleeve insert.

TL;DR: In this article, the authors investigated the potential failure mechanisms of composite repairs and assisted in the development of a certification methodology for both civil and aircraft structures and showed that interlaminar failure, in the case of composite repair to aircraft structures, and shear failure in the concrete, in case of repairs to degraded concrete structures, can often drive the design process.

TL;DR: In this paper, the authors present the results of a numerical investigation into the use of piezoelectric sensors to monitor crack growth beneath a boron/epoxy patch.
Abstract: Boron/epoxy composite patches are being increasingly used to repair damaged structural components. With the increased attention currently being given to the certification of repairs the question of damage tolerance needs to be addressed. Piezoelectric sensors offer the potential for detecting and monitoring damage both in and beneath a boron/epoxy repair. This report presents the results of a numerical investigation into the use of piezoelectric sensors to monitor crack growth beneath a boron/epoxy patch.

TL;DR: In this article, the Ramaswamy-Stouffer-Laflen constitutive model has been extended to account for the inelastic response of T7451 aluminium alloy to complex load spectra.
Abstract: The Ramaswamy-Stouffer—Laflen constitutive model (1) has recently been extended (2) to account for the inelastic response of 7050—T7451 aluminium alloy. This paper presents the results of a combined analytical and experimental investigation into the ability of this model to predict the inelastic response to complex load spectra.

TL;DR: In this paper, the authors present an overview of the structural aspects of the design and development of a local reinforcement designed to lower the stresses in a region of the F-111C wing fitting which is prone to cracking.
Abstract: This paper presents an overview of the structural aspects of the design and development of a local reinforcement designed to lower the stresses in a region of the F-111C wing fitting which is prone to cracking. The stress analysis, with particular emphasis on the use of a unified constitutive model for the cyclic inelastic response of the structure, representative specimen testing, thermal analysis and full scale static testing of this design are summarized.
