Fracture mechanics analyses of the slip-side joggle regions of wing-leading-edge panels
Journal Title: Frattura ed Integrità Strutturale - Year 2011, Vol 5, Issue 15
Abstract
The Space Shuttle wing-leading edge consists of panels that are made of reinforced carbon-carbon. Coating spallation was observed near the slip-side region of the panels that experience extreme heating. To understand this phenomenon, a root-cause investigation was conducted. As part of that investigation, fracture mechanics analyses of the slip-side joggle regions of the hot panels were conducted. This paper presents an overview of the fracture mechanics analyses.

Estimation of fatigue lifetime for selected metallic materials under multiaxial variable amplitude loading
This paper initially investigates the accuracy of two methods, i.e., the Maximum Variance Method (MVM) and the Maximum Damage Method (MDM), in predicting the orientation of the crack initiation plane in three...
Integrated assessment procedure for determining the fracture strength of glass components in CSP systems
The structural integrity and reliability of glass components are key issues for concentrated solar power (CSP) systems. For example, the glass windows in a solar furnace may suffer catastrophic fracture due to th...
Fatigue life estimation in welded joints under multiaxial loadings
Welded joints are frequently locations for cracks initiation and propagation that may cause fatigue failure of engineering structures. Biaxial or triaxial stress-strain states are present in the vicinity of welded joint...
A numerical study of two different specimen fixtures for the modified compact tension test – their influence on concrete fracture parameters
The modified compact tension test (MCT) may represent a new test configuration for the performance of static and other kinds of fatigue tests on concrete-like materials. Core drilling can be employed to obtai...
Experimental investigation of effect of specimen thickness on fracture toughness of Al-TiC composites
In this paper, the macro and micro-mechanical fracture behavior was studied for aluminum (Al6061) alloy matrix, reinforced with various proportions of TiC particles such as 3wt%, 5wt% and 7wt%. The Al6061-TiC...
