NOTE: Lujax tmi is going to interrupt its functions shortly and these web pages may not be
available after a while. If you find this applet/application useful, please download and save the runnable platefem.jar Java application from this link.
If your Java environment is correctly
installed, you should be able to run the application platefem.jar by double clicking its
icon or alternatively, by issuing command java -jar platefem.jar in your
terminal. If you are interested to maintain platefem web pages in the future, please contact me ASAP!
This Java 2 -applet / application calculates rectangular, thin plate vibration and buckling modes and corresponding eigenvalues and -frequencies with appropriate boundary conditions.
The applet uses finite element method (FEM) with Kirchhoff thin plate plate assumption, I.e., the through thickness shear deformations are negligible. Further, the deformations are assumed to be small and linearity is thus maintained.

Some
calculated result modes
The FE-mesh is composed of regular mesh of rectangular plate elements with cubic shape functions. Boundary conditions and buckling edge loads may be given for the mesh edges. Orthotropic or general anisotropic material bending matrix may be input directly and its orientation may be adjusted as desired.
The applet requires a recent Java applet plug-in to be installed and activated in the used web browser (otherwise, the applet frame will not be shown or it is shown grayed). If needed, an appropriate java plug-in may be downloaded from, for example, Sun Inc.:s homepages.
