Overview

eLamX is a freeware, Java-written composite calculator, which is being developed at Technische Universität Dresden, Institute of Aerospace Engineering, Chair of Aircraft Engineering. Calculations are based on the classical laminated plate theory. At present modules for composite calculation including hygrothermal effects, failure analysis and engineering constants, stability and deformation analysis of composite plates, comparison of a multitude of failure criteria and the World-Wide Failure Exercise are implemented. Additional modules dealing with micromechanics, nonlinear calculations, sandwich structures and composite plate vibration are planned or under development.
