The present work demonstrates the use of peridynamic equations to capture dynamic crack patterns observed during experimental tests performed in concrete and polymethylmethacrylate (PMMA) materials. In the first part of the work, two concrete specimen configuration, namely a compact tension and a L-specimen, are modeled at different dynamic loading rates. In the second part the effect of having a weaker interface in between a PMMA plate is simulated and compared, with the case of not having an interface at all. In both, it is observed that simulation provides good agreement with experimental results.

Abstract
The present work demonstrates the use of peridynamic equations to capture dynamic crack patterns observed during experimental tests performed in concrete and polymethylmethacrylate (PMMA) materials. In the first part of the work, two concrete specimen configuration, namely a compact tension and a L-specimen, are modeled at different dynamic loading rates. In the second part the effect of having a weaker interface in between a PMMA plate is simulated and compared, with the case of not having an interface at all. In both, it is observed that simulation provides good agreement with experimental results.File in questo prodotto:
