WebK Fixed-Pinned Beam Beam mass only Eigenvalue Reference 1. T. Irvine, Application of the Newton-Raphson Method to Vibration Problems, Revision E, Vibrationdata, 2010. 4 APPENDIX A Cantilever Beam I Consider a mass mounted on the end of a cantilever beam. Assume that the end-mass is much greater than the mass of the beam. ... WebEigenvalue problem typically contains a bunch of eigenpairs, usually even infinitely many (but in most system relevant to physics, numerably infinitely many, so the eigenvalues are quantized). Therefore, the PINN for eigenvalue problem should; simultaneously optimize on the eigenvalue and the eigenfunction;
