Dynamic strength characteristics of materials: influence of the specimen size on strain rate

Test results are presented for an additive material prepared of acrylonitrile-butadiene-styrene on a 3$D$ printer. Dynamic tension experiments have been carried out using a tower-type drop hammer with an accelerator. Data obtained from different specimens demonstrate that high-strain-rate tensile experiments are feasible if the working part of the specimen is decreased. A theoretical analysis of test data using the incubation time criterion has been performed, and it has been found that analytical results are in good agreement with experimental data.
