Monitoring Microstructural Evolution and Crack Formation in a Solid Propellant under Incremental Strain Condition- Using Digital Radiography X-Ray Techniques

Abstract

In this study, the change of microstructure and the formation of cracks in a solid propellant under an incremental strain loading condition were investigated using digital radiography x-ray techniques. Experimental findings revealed that the degree of in homogeneity of the material's microstructure and the number of non-propagating cracks increased as the applied strain was increased. Also, the strain distribution was highly non-uniform when the applied strain was high.
