The interlayer approximates the matrix-rich interlaminar region containing the crack. The stiffness matrix approach is utilized and the current crack problem is reduced to solving a system of singular integral equations. The singular response of an interlaminar crack to in-plane normal, in-plane ...
the stiffness matrix. The intention with this is to constrain loose parts that are initially close but not in contact by pushing out the contact surface usingSFSTand applying theIGNORE=2option. It is at least good for debugging problems with many singular rigid body modes.IGNORE=3is the ...

Since the basis is Riesz, the stiffness matrix is well-conditioned, uniformly in the index subset. Consequently, the Galerkin system can be solved by the application of a simple iterative scheme. Due to the anisotropic nature of the basis functions, the stiffness matrix is, however, generally ...
and similarly for the degrees of freedom, NaN/Inf in the matrix columns So does this means that the ComSol model is correct, but the simulation result found some singular point or what? I have attached the ComSol model file in the attachment. ...

Moreover, the information contained in the singular vectors provided via the FDD algorithm at the position of each local maxima provided the coordinates of the modal shapes related to each frequency (Fig. 11). Fig. 10 First singular value of the spectral matrix (solid line), coherence (dashed...
{\Delta t}corresponding to the Newmark method. Otherwise, the procedure outlined in Sect.2can be applied, while taking into account that the2n+1DoF system is treated as a block matrix equation, thus the differentiations and series expansions have to be carried out in a scalar (\tau) or ...
