Concrete mixed mode fracture test CARPIUC Benchmark « Predefined loadings » NP2 & P4
<p>The following data can be used for <strong>benchmarking numerical simulations of crack propagation test on quasi-brittle materials</strong>.</p> <p>Two crack propagation tests are proposed here, close to the well-known Nooru-Mohamed tests, but with modern instrumentation so that they provide trustworthy data. They present <strong>initiation and propagation</strong>. The goal is to compare your simulation results with the measured <strong>crack paths</strong> and <strong>force-displacement curves</strong>.</p> <p>The input data consists in specimen geometry, experimentally determined material properties (Young modulus, tensile strength, compressive strength and fracture energy) and the <strong>measured boundary conditions</strong>.</p>
