Periodic solutions of a piecewise linear beam equation with damping and nonconstant load. <i>Electronic Journal of Differential Equations, 2002</i>(81), pp. 1-12.1072-6691https://hdl.handle.net/10877/12414Using the Lyapunov-Schmidt reduction method, the authors discuss the existence and multiplicity of periodic solutions for a piecewise linear beam equation with damping and nonconstant load when the nonlinearities cross the eigenvalues. The result answers partially an open question possed by Lazer and McKenna [12].Text12 pages1 file (.pdf)enAttribution 4.0 InternationalPiecewise linear beam equationDampingPeriodic solutionLyapunov-Schmidt reductionArticle
