Numerical Determination of Delamination Onset in Laminated Symmetric DCB Specimen
In this study, a novel numerical method is proposed for determination of mode-I interlaminar fracture toughness, GIc, in multi-directional (MD) double cantilever beam (DCB) specimens using fracture properties of unidirectional DCB specimens. Two factors, β and Dc are defined to minimize the undesirable effects on strain energy release rate. β describes the difference between maximum and average...
متن کاملFracture Behavior of Multidirectional DCB Specimen: Higher-Order Beam Theories
Mathematical models, for the stress analysis of symmetric multidirectional double cantilever beam DCB specimen using classical beam theory, first and higher-order shear deformation beam theories, have been developed to determine the Mode I strain energy release rate SERR for symmetric multidirectional composites. The SERR has been calculated using the compliance approach. In the present study, ...
متن کاملFinite Element Simulation of Fast Fracture in Steel Dcb Specimen
Abstract--Results of a numerical simulation, based on an energy consistent moving singularity dynamic finite element procedure, of fast crack propagation and arrest in a high strength steel DCB specimen are presented. The influence of material properties of high strength steel on dynamic crack propagation and arrest is investigated. The influence of the loss of constact of specimen with the loa...
متن کاملDiscrete Spring Model for Predicting Delamination Growth in Z-Fiber Reinforced DCB Specimens
Beam theory analysis was applied to predict delamination growth in DCB specimens reinforced in the thickness direction with pultruded pins, known as Z-fibers. The specimen arms were modeled as cantilever beams supported by discrete springs, which were included to represent the pins. A bi-linear, irreversible damage law was used to represent Z-fiber damage, the parameters of which were obtained ...
متن کاملSpecimen-specific Modelling of Cervical Vertebrae in Axial Compression
INTRODUCTION Finite element (FE) models of the cervical spine are needed to evaluate injury prevention devices and to improve our understanding of vertebra fractures, which may injure the spinal cord. However, current FE cervical spine models typically do not incorporate trabecular bone heterogeneity or geometrical differences between spines; therefore, the models are not able to address questi...
