The double cantilever beam test applied to mode I fracture characterization of cortical bone tissue.
The primary objective of this work was to analyse the adequacy of the Double Cantilever Beam (DCB) test in determining fracture toughness under pure mode I loading of cortical bone tissue. A new data reduction scheme based on specimen compliance and the crack equivalent concept was used to overcome the difficulties inherent in crack monitoring during its growth. It provides a complete resistanc...

متن کاملDetermining Effective Interface Fracture Properties of 3D Fiber Reinforced Foam Core Sandwich Structures
Foam core sandwich composites are finding a wider breadth of use in aerospace, automotive, and construction applications. These structures present unique challenges in terms of material failure and interaction and are highly sensitive to damage and imperfections introduced during manufacturing. An emerging class of 3D Fiber Reinforced Foam Core (3DFRFC) aims to replace monolithic foams used in ...
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 کاملNeurocontrol of a Cantilever Beam
The civil engineering community is currently moving towards the continuous monitoring of civil structures in order to forecast their unavoidable failure with enough precision. So-called smart technologies seem to be well adapted to this specific task. For a civil structure, such as a bridge or a dam, a monitoring smart system often includes a set of sensors, whose data is passed onto a controll...
