- •
Indenter nose shape sensitivity of quasi-static perforation is investigated by analytical and numerical approaches.
- •
In general, model predictions match experimental results reasonably well over a wide range of nose shapes.
- •
Limitations of each modelling approach are discussed.
- •
Careful consideration of material anisotropy, indenter-plate friction and boundary compliance is necessary.
- •
The Lode angle dependency is essential for predicting the indentation response across a wide range of tip geometries.
