Predicting the crack path in a wedge under a concentrated tensile force by means of variational principle

Yury Matvienko, Nataliya Popova, Evgeny Morozov

Variational principle of brittle fracture mechanics is employed to predict the crack path in an infinite wedge under a concentrated tensile force. The weight function in basic equation of variational problem is assumed to be proportional…

A 3D mixed frame element with multi-axial coupling for thin-walled structures with damage

D. Addessi, P. Di Re

A 3D mixed beam finite element is presented, modeling the warping of the cross-sections as an independent kinematic field. The beam formulation is derived on the basis of the Hu-Washizu variational principle, expressed as function of four…

Mixed methods for viscoelastodynamics and topology optimization

Giacomo Maurelli, Nadia Maini, Paolo Venini

A truly-mixed approach for the analysis of viscoelastic structures and continua is presented. An additive decomposition of the stress state into a viscoelastic part and a purely elastic one is introduced along with an Hellinger-Reissner…

On one approach to the numerical modeling of the strain-stress state of layered rock mass

Sergey Yurevich Lobanov, Alexander Baryakh

According to the principle of virtual work for a system of elastic layers, a semi-analytical scheme for constructing the finite-dimensional analog of the variational equation was developed based on the well-known analytical solution in the…
