• Crack Modeling for Structural Health Monitoring (2002, methodology): “The cracked beam discussed earlier is modeled using 20 elements, and the open crack is modeled using the approach of Sinha et al. (2002). Five modes are retained to calculate the response, and an impulse force at the tip of the beam is simulated using a half sine pulse of magnitude 100N and duration”
• Multi-cracked Euler-Bernoulli beams: Mathematical modeling and exact solutions (2013, background): “In the case of beams under plane flexural deformation, for example, a notch or a crack is modeled by inserting a massless, rotational elastic spring at the damaged cross section (Gudmnundson, 1983; Sinha et al., 2002).”
• Numerical analysis of cracked beams using nonlinear output frequency response functions (2008, methodology): “[14], the matrix 1⁄2Kc is”
• Cracked beam identification by numerically analysing the nonlinear behaviour of the harmonically forced response (2011, background): “In the local flexibility models [30,31,25,15,10,32], the main idea in modelling the crack is to introduce a local compliance matrix, connecting longitudinal, bending and shear forces and displacements near the crack tip; the elements of the local flexibility matrix describe the reduced stiffness due”
• Exact solution of the multi-cracked Euler–Bernoulli column (2008, background): “On the contrary, a stiffness reduction with a local effect governed by a triangular variation has been proposed by Sinha et al. (2002).”
