The Integrated Composite Analyzer with Damping Capabilities (ICAN/DAMP) combines the comprehensive linear analysis of multilayered fiber composites in ICAN (COSMIC programs LEW-15832, LEW-15592) with the prediction of damping in polymer-matrix composites. Like ICAN, the analysis contains the essential features required to effectively design structural components made from fiber composites, including micromechanical design features to predict ply-level hygral, thermal, and mechanical properties, and laminate analysis features to account for interply layer effects. ICAN/DAMP incorporates a new module for synthesizing the material damping from micromechanics to the laminate level.
In ICAN/DAMP, explicit micromechanics equations based on hysteretic damping are programmed to relate the on-axis damping capacities to the fiber and matrix properties and fiber volume ratio. The damping capacities of unidirectional composites subjected to off-axis loading are synthesized from on-axis damping values. The hygrothermal effect on the damping performance of unidirectional composites caused by temperature and moisture variation is modeled along with the damping contributions from interfacial friction between broken fibers and matrix. The temperature rise in continuously vibrating composite plies and composite laminates is also estimated.
ICAN/DAMP is written in FORTRAN 77 for AMDAHL 5870 series computers running the VM/SP operating system. Sample input and output are provided. ICAN was developed in 1986 and ICAN/DAMP was released in 1994.
