Dynamic Analysis of the Elastic Composite in the Shape of the Human Heart

Lukáš Jiran, Marek Štefan, Tomáš Mareš

Abstract


This work deals with a dynamic deformation analysis
of the thick-walled closed anisotropic model whose geometry
and cross-section are motivated by human heart shape. The
oscillations of the model are solved using the action integral,
EulerLagrange equations for the action integral and the singular
value decomposition. The action integral is determined using
the semi-analytical method, anisotropic elasticity in curvilinear
coordinates and the Fourier series expansion.

Keywords


dynamic analysis; action integral; oscillation; heart; anisotropic
