Summary on Grant Application Form |
|
The increasing use of advanced composites in a wide range of industries, from advanced design of aircraft components (and recently primary aircraft structures) to low cost mass produced leisure goods, requires a detailed understanding of the behaviour of the composite component or structure to a wide range of potential loadings, some of which may be severe and catastrophic for component or structure.General purpose numerical tools are now routinely available for analysing conventional composite structures, but are still unavailable for modelling or analysing severe loadings, such as impact followed by penetration, which can be expensive and time consuming to experimentally test.The thrust of the proposal is the development of a non-linear composite failure model based on a damage mechanics approach. The damage mechanics approach does not require any initial flaw, and hence overcomes the initiation problem. The new material model will be implemented into the industrial standard FE code DYNA3D. The modified DYNA3D FE code will then be used to model high strain-rate tests.
