DST contributions to the F-35 Joint Strike Fighter program

The F-35A Joint Strike Fighter will deliver to Australia the world’s most advanced and capable multi-role fighter; a fifth-generation aircraft that offers an unparalleled mix of situational awareness, stealth and mission capabilities.

Copolymer Toughening of Epoxy Resin Systems for Low Temperature Cure Bonded Composite Repair

Epoxies are the most widely used resins for bonded composite repair; however they possess low fracture toughness, impact strength and peel strength due to high cross linking densities. In this work, the impact of two commercially available tri-block copolymers on the mechanical performance of two different low temperature cure epoxy resin systems are evaluated.

Review of Battery Technologies for Military Land Vehicles

This report provides an overview of battery technologies and related issues relevant to their use in military land vehicles.

Beta Factors for Collinear Asymmetrical Cracks Emanating from an Offset Circular Hole in a Rectangular Plate

Using a custom-written FORTRAN computer program, interfaced with an existing two-dimensional boundary element fracture analysis code, the present report provides an extensive set of Beta factor solutions covering a wide range of hole offsets and crack lengths. This work has also led to the derivation of an improved closed-form analytical two-dimensional Beta factor solution for the related case of symmetrical cracks emanating from a central hole in a finite-width strip.
