Measurement of High Strain Regions in Particulate Composites Using Digital Image CorrelationProceedings of the Tenth US-Japan Conference on Composite Materials
Document TypeConference Proceeding
AbstractThis paper presents a methodology for the measurement of high strain regions in particulate composites used as rocket fuel. It is shown that there is statistical distribution of high strain regions through out a strained material. A theory is developed to determine the threshold that determines the identification of the high strain regions. It is shown that by using this approach it is possible to identify high strain regions that eventually lead to failure. These high strain regions are determined experimentally by using a high digital image correlation approach. This work may be used to identify very early on regions of eventual failure, and may also be used to change the distribution of the particles in the composite so as to obtain improved material properties.
