Aviation research, sourced & cited.

Curated index of aviation-relevant research from NASA NTRS, NTSB safety studies, FAA CAMI, and academic sources. Every record links back to its original — we don't host PDFs, we describe each paper and credit the authors. Built for cross-link with the rest of Atlas: search by topic, drill into a CFR section or airframe and see the research that bears on it.

Investigation of Micro-Scale Architectural Effects on Damage of Composites

This paper presents a three-dimensional, energy based, anisotropic, stiffness reduction, progressive damage model for composite materials and composite material constituents.
NASA NTRS 2019 CDMS Conference Paper

Certification of damage tolerant composite structure

A reliability based certification testing methodology for impact damage tolerant composite structure was developed. Cocured, adhesively bonded, and impact damaged composite static strength and fatigue life data were stat…
NASA NTRS 2016 CDMS Conference Paper

Tensile strength of composite sheets with unidirectional stringers and crack-like damage

The damage tolerance characteristics of metal tension panels with riveted and bonded stringers are well known. The stringers arrest unstable cracks and retard propagation of fatigue cracks.
NASA NTRS 2016 CDMS Conference Paper

Comparison of toughened composite laminates using NASA standard damage tolerance tests

The proposed application of composite materials to transport wing and fuselage structures prompted the search for tougher materials having improved resistance to impact damage and delamination.
NASA NTRS 2013 CDMS Conference Paper

Impact damage in composite laminates

Damage tolerance requirements have become an important consideration in the design and fabrication of composite structural components for modern aircraft.
NASA NTRS 2011 CDMS Conference Paper

Damage tolerance research on composite compression panels

The damage tolerance of composites was investigated. Results show that severe degradation in material strength may occur due to impact damage and that reduced strain allowables should be considered to compensate for poss…
