Material testing 2.0 for composites

Most of the current material testing procedures and standards have been designed at a time when camera-based full-field measurements were not available and only point-wise sensors could be used, like extensometers or strain gauges. As a consequence, such test configurations rely on simple strain fields (uniform, linear) that can easily be approached with such point sensors, and statically determinate stress solutions to obtain local stress information from global load-cell readings. While such tests are easy to analyse, they rely on strong assumptions on boundary conditions and specimen homogeneity, and are poor in contents, leading to the need for numerous test configurations to be used to calibrate complex constitutive models.

Abstract: Most of the current material testing procedures and standards have been designed at a time when camera-based full-field measurements were not available and only point-wise sensors could be used, like extensometers or strain gauges. As a consequence, such test configurations rely on simple strain fields (uniform, linear) that can easily be approached with such point sensors, and statically determinate stress solutions to obtain local stress information from global load-cell readings. While such tests are easy to analyse, they rely on strong assumptions on boundary conditions and specimen homogeneity, and are poor in contents, leading to the need for numerous test configurations to be used to calibrate complex constitutive models.
