Description

HPM (Hybrid-type Penalty Method) is suite to represent failure phenomena of transition from continua to discontinua such as concrete material. Initiation and propagation of dominant cracks and branch of crack can easily be modeled as discrete crack. The HPM represent discrete crack by eliminating penalty that represents separation of the elements at the boundary. This treatment is easy since no change of degrees of freedom for discrete crack is necessary. In addition to that, it is important to evaluate correct deformation of continua before crack takes places. To achieve this, the authors implemented a constitutive model of concrete material to the HPM. In this report, we explain implemented constitutive model and show a simulation of anchor-bolt pullout test using the HPM demonstrating the capability of evaluating progressive failure.
