A homogenised continuum constitutive model for visco-plastic deformation of uni-directional composites

This research was targeted at developing understanding and predictive models for high rate blast loading. The work aimed to develop a constitutive model which captures full orthotropic behaviour of a laminated composite by employing nine material parameters and accounting for strain-rate sensitivity to loading. The formulation is an extension of the work by Ogihara and Reifsnider. The model developed accounts for strain-rate dependence and can be used for various composite architectures, including woven and uni-directional. The model is being studied by Dstl (Dr Dan Pope) for its potential to predict realistic blast loading in real life scenarios.
