Derivative-orthogonal non-uniform B-Spline wavelets
(2021)This paper attempts to merge the concept of hierarchical finite element analysis (FEA) into isogeometric analysis (IGA). The proposed methodology replaces the traditional grid refinement of IGA with custom enrichment ... -
Finite element methods for piezoelectricity and flexoelectricity with fracture mechanics applications
(2017)Flexoelectricity is the coupling of polarization to strain gradients. This effect is size-dependent and is most prominent in nanoscale structures in which gradients are large. In our previous work, we have established a ... -
Hierarchical Bayesian uncertainty quantification of dynamical models utilizing modal statistical information
(2020)Updating dynamical models based on experimental modal information has become an important topic in structural health monitoring. This paper revisits this significant problem and develops a new two-stage hierarchical Bayesian ... -
Size effects in two-dimensional layered materials modeled by couple stress elasticity
(2021)In the present study, the effect of material microstructure on the mechanical response of a two-dimensional elastic layer perfectly bonded to a substrate is examined under surface loadings. In the current model, the substrate ... -
A variable impedance control strategy for object manipulation considering non-rigid grasp
(2020)This paper presents a novel control strategy for the compensation of the slippage effect during non-rigidly grasped object manipulation. A detailed dynamic model of the interconnected system composed of the robotic ...
