Analytical corrections for double-cantilever beam tests

چکیده
Abstract Double-cantilever beams (DCBs) are widely used to study mode-I fracture behavior and measure toughness under quasi-static loads. Recently, the authors have developed analytical solutions for DCBs dynamic loads with consideration of structural vibration wave propagation. There two methods beam-theory-based data reduction determine energy release rate: (i) using an effective built-in boundary condition at crack tip, (ii) employing elastic foundation model uncracked interface DCB. In this letter, corrections a crack-tip rotation presented, afforded by combining both these data-reduction authors’ recent each. Convenient easy-to-use DCB tests obtained, which avoid complexity difficulty approach, need multiple experimental measurements compliance length. The are, best knowledge, completely new. Verification cases based on numerical simulation presented demonstrate utility corrections.

Neurocontrol 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...
متن کاملAnalytical Corrections for Beam-hardening and Object Scatter in Volumetric Computed Tomography Systems
The advent of the use of digital area detectors in Volumetric Computed Tomography (VCT) systems has brought with it the challenges of achieving image quality comparable to that provided by earlier planar industrial CT systems equipped with highly collimated and efficient linear detector arrays. Particularly for imaging with higher voltage x-ray sources up to 450kVp, among the most distinct imag...
