International audienceThe article reports experiments using the Taylor test to define the dynamic behavior of brass. This material does not exhibit strain rate dependency therefore it allows the validation of an analytical description of flow stress as a function of strain with strain hardening for the data obtained from the Taylor test. The experiment is used to study the process of damage and fracture with fragmentation which is dependent on the impact velocity. Using the experimental data a numerical model of the Taylor test is developed to determine the strain level and the strain gradient along the specimen
