Tensile damage response from discrete element virtual testing
Depending on the loading conditions on brittle materials, damage can generally not be reduced to a simple scalar. Microcrack orientation affects the stiffness in a preferential direction perpendicular to the crack lips. Taking into account the damage anisotropy in phenomenological models is a possible option, but the identification of the corresponding models with respect to damage anisotropy i...

Porto, the institutional repository of the Politecnico di Torino, is provided by the University Library and the IT-Services. The aim is to enable open access to all the world. Please share with us how this access benefits you. Your story matters. Abstract. In this work, an optimization based approach presented in [5, 6, 7] for Discrete Fracture Network simulations is coupled with the Virtual El...
متن کاملNumerical study of bending test on compacted clay by Discrete Element Method: tensile strength determination
The study of the tensile behaviour of clay is one of the topics which requires a specific lighting especially when one pays a close attention to the pathology of work built with or on clays subjected to significant tensile forces. Therefore, failure or damage of clay, under specific conditions, can be related to tensile stress limit and not to shear stress limit. It is the case of compacted cla...
متن کاملDynamic tensile testing of ligaments from the human cervical spine
This study focuses on establishing appropriate experimental methodology to facilitate investigation of the dynamic stress-strain characteristics of soft bio-tissues. Dynamic mechanical tests were conducted on ligaments from the human cervical spine (neck), using a tensile split Hopkinson bar device. The strain rates imposed were of the order of 10~10/s. As ligaments are extremely soft and exten...
متن کاملDetermination of load-bearing element length in paper using zero/short span tensile testing
This study presents an equation developed to estimate, from zero and short-span tensile tests, the average length of load-bearing elements (the distance between serious defects along a fiber length) within a sheet of paper. The equation was used to examine the effect of drying treatment on the average loadbearing element length in paper made from five furnishes: two radiata pine kraft pulps, a ...
