Investigation of large area sheet forming with laser shocking spot by spot

The paper presents a large-bottom cup formed by multiple-spot laser shocking. A 3D finite element model was developed with computational hardware and software resources to simulate the shape evolution process of cup manufactured by gradual-increasing-shot laser shocking along a specified path. A ser...
