Continuum damage modeling of delamination in paperboard
This work concerns the creasing and folding of a continuum paperboard material model developed by Eric Borgqvist. Creasing is an operation that induces permanent deformation in the material, undertaken for the folding to be performed along a straight fold line without any in-plane cracks. The material model concerned is complex and involves a high degree of anisotropy, and it has earlier been prov
