Summary on Grant Application Form |
|
The behaviour of three cellular materials having considerable potential as impact energy absorbers will be investigated in an extensive experimental programme. The aim will be to subject them to uniaxial compression over a wide range of impact loading conditions and examine their response in detail. The velocity dependance of the magnitudes of the stresses generated will be examined and quantified to assist material selection for impact applications. Particular attention will be paid to the nature of and changes in their deformations mechanisms. A number of experimental techniques will be used to cover the range of loading conditions and one aim will be to define suitable methods of measuring reliably the high rate properties of this class of materials. Coupled with the experimental programme will be a thorough investigation into methods for modelling the response of these materials. Based on the experimental results, suitable theoretical frameworks based on continuum mechanics and/or discrete formulations will be sought to describe the deformation of each of the materials. Enhanced wave models, computational models based on finite element methods and discrete element models will be examined and developed. The overall aim is to produce a reliable and comprehensive description of the constitutive behaviour of these important materials at high loading rates for incorporation into materials and structural modelling tools to assist designers involved in safety-sensitive applications.
