The classic snap-through problem of shallow arches is revisited using the so-called
generalised path-following technique. Classical buckling theory is a popular tool for
designing structures prone to instabilities, albeit with limited applicability as it assumes a
linear pre-buckling state. While incremental-iterative nonlinear finite element methods are
more accurate, they are considered to be complex and costly for parametric studies. In this
regard, a powerful approach for exploring the entire design space of nonlinear structures is …
