Figure 1. Schematic for wave propagation in a bar.
To make the problem a one-dimensional strain problem, all four lateral faces
are on rollers; thus, the three-dimensional model simulates a one-dimensional
problem. The material is steel with the properties shown in
Figure 1.
The free end of the bar is subjected to a blast load with a magnitude of 1.0 ×
105 Pa and a duration of 3.88 × 10−5 s. The normalized
load versus time is shown in
Figure 2.
