Article Synopsis
- This article discusses the modeling of high-strength steel SZBS800's response to strain rates using a combination of standard tensile tests and a unique method involving shooting a ball into specimens.
- The authors employed the Cowper-Symonds viscoplastic model to factor in strain-rate effects and estimated its parameters through a systematic procedure involving rough estimates and fine-tuning techniques.
- Optimal parameter values were determined using explicit dynamic simulations and a genetic algorithm, effectively capturing the material's response, although the optimal candidates spanned a wide range for some parameters.
