Kirchhoff-Love shells within strain gradient elasticity: weak and strong formulations and an H3-conforming isogeometric implementation
Balobanov, Viacheslav; Kiendl, Josef; Khakalo, Sergei; Niiranen, Jarkko (Journal article; Peer reviewed, 2018)A strain gradient elasticity model for shells of arbitrary geometry is derived for the first time. The Kirchhoff–Love shell kinematics is employed in the context of a one-parameter modification of Mindlin’s strain gradient ... -
Variational formulations, model comparisons and numerical methods for Euler–Bernoulli micro- and nano-beam models
Niiranen, Jarkko; Balobanov, Viacheslav; Kiendl, Josef; Hosseini, S. B. (Journal article; Peer reviewed, 2017)As a first step, variational formulations and governing equations with boundary conditions are derived for a pair of Euler–Bernoulli beam bending models following a simplified version of Mindlin’s strain gradient elasticity ...
