One of the most common failure modes of strengthened RC beams with externally bonded FRP is intermediate crack (IC) debonding of FRP initiated at the tip of flexural/shear cracks. This study presents a method, using extended finite element method (XFEM), to model IC debonding in an FRP-strengthened concrete beam. In XFEM, as soon as a damage initiation criterion is reached in an element, additi...

Abstract To prevent construction machinery from intruding into the transmission corridor during operation and causing damage to normal of line, this paper uses relationship between horizontal distance boom measurement point at minimum safe distance, angle ground field strength as a comprehensive criterion carry out an early warning line breaking. The method studied in can provide simple accurat...

Under external load excitation, damage such as breathing cracks and bolt loosening will cause structural time domain acceleration to have nonlinear features. To solve the problem of identification, a identification method based on Kullback–Leibler (KL) distance model residuals is proposed in this paper. First, an autoregressive (AR) order was selected using autocorrelation function (ACF) Akaike...

in this paper, the capabilities of displacement curvature derived from static response data for finding the location and severity of damage in euler-bernoulli beams are assessed. static response of a beam is obtained using the finite element modeling. in order to reduce the number of measured nodal displacements, the beam deflection is fitted through a polynomial function using a limited number...

In rock engineering, damage evolution upon loading imposes significant impacts on the stiffness of mass and its deformation characteristics. order to investigate influence both plasticity cavity expansion, a plastic solution is derived for undrained spherical expansion in medium. For consideration plasticity-damage, Modified Cam-Clay (MCC) model selected as driver, criterion adopted coupled wit...

Systemic lupus erythematosus (SLE) is a systemic inflammatory disease secondary to an autoimmune response that characterized by the deposition of immune complexes activate complement and cause tissue damage. The American College Rheumatology (ACR, Rheumatology) in 2012 established new diagnostic criteria for SLE, identifying 17 which at least 4 must be met (at one clinical, immunologic) or neph...
