Material Testing 2.0

An introduction to Material Testing 2.0

At present, material testing is still mostly performed through standards developed for extensometers or strain gauges, using simple geometries with statically determinate stress states. These tests provide a limited amount of information per test and lead to the need for a large number of tests to calibrate a given material model. This is in stark contrast with numerical simulation, which has seen spectacular progress in the last decades. It is therefore essential to develop the next generation of data-rich image-based tests, coined ‘Material Testing 2.0’.

The attached figure illustrates this new paradigm. While a uniaxial tensile test provides one data point per load step, MT2.0 tests provide the equivalent of one MT1.0 test for each measurement point, resulting in an immensely richer database from which models can be better and more efficiently calibrated.
