Literature-based impact demonstration

Taylor bar impact
227 m/s

A copper cylinder strikes a frictionless planar rigid wall at 227 m/s. Watch its impacting end spread while plastic strain develops, through 80 µs of simulated time.

One quarter of the bar is shown as computed, without mirroring or displacement enlargement. The two flat faces are symmetry planes. The translucent grey disc illustrates the planar rigid wall. Effective plastic strain uses a fixed 0–2.5 color scale; values above 2.5 use the top color.

The impacting end spreads from an initial radius of 3.20 mm to 7.33 mm. Maximum cell-averaged effective plastic strain is 3.45. These values describe this simulation, rather than differences from a reference solution.

Model and loading

Copper bar

Initial length 32.4 mm and radius 3.2 mm. The quarter model has 4,050 Hex8 · F-bar elements (2 × 2 × 2 integration) and 5,005 nodes, with symmetry constraints on two planes.

Rigid-wall impact

The bar starts with a uniform axial velocity of 227 m/s toward a stationary, frictionless planar rigid wall. The material uses elastic–plastic response with linear isotropic hardening.

What the result establishes

The run reaches the specified 80 µs end time. The reported geometry is the saved state at that time; it is not an independent experimental or analytical accuracy comparison.

This configured example demonstrates solid plasticity and planar rigid-wall impact. It provides no calibrated error metric, mesh-convergence result or proof of rate-dependent material behavior.

Model origin and literature

These results use a MinuteSim-generated mesh and input deck. Geometry and copper material values follow the Taylor impact example in §4.3.2 of arXiv:2602.15149. That reference uses a different numerical method; it supplies model parameters here, not a comparison result.

The classical test is associated with Taylor (1948) and Wilkins and Guinan (1973). The figures and videos on this page are MinuteSim simulation outputs.
