摘要：

The hybrid-type penalty method (HPM) is suitable for representing failure phenomena that occur during the transition from continua to discontinua in materials such as concrete. The initiation and propagation of dominant cracks and the branching of cracks can easily be modeled as discrete cracks. The HPM represents a discrete crack by eliminating the penalty that represents the separation of elements at the intersection boundary. This treatment is easy because no change is required in the degrees of freedom for the discrete crack. We present a numerical method of a constitutive model of concrete for application of the hybrid-type penalty method (HPM), and describe the simulation of an anchor bolt pullout test and deep beam test using fine meshes and Delaunay triangulation to validate of the method for evaluating progressive failure.
