Manual of GUI Program Governing ABAQUS Simulations of Bar Impact Test for Calibrating Bar Properties, Measured Strain, and Impact Velocity

Bar impact instruments, such as the (split) Hopkinson bars and direct bars, measure blast/impact waves or mechanical properties of materials at high strain rates. To effectively use it is essential to know (i) elastic bar, (ii) correction factor measured strain, (iii) information on velocity. This paper presents a graphic-user-interface (GUI) program prepared for solving these fundamental issues. We describe directory structure program, roles relations associated files, GUI panels, algorithm, execution procedure program. employs separately bar density value governs ABAQUS simulations (explicit finite element analyses) test given velocity range (elastic modulus Poisson’s ratio) two factors (in compression tension) strain. The simulation repeated until predicted wave profile in reasonably consistent with experimental counterpart. are determined calibrated values when profiles consistent. also capable calibration reference reliably wave. quantities 19.1 mm diameter (maraging steel) were successfully using presented auxiliary programs, pre-processing an example input file available publicly accessible data repository.
