A novel hybrid isogeometric element based on two-field Hellinger-Reissner principle to alleviate different types of locking
Dhiraj S. Bombarde, Sachin S. Gautam, Arup Nandy
In the present work, a novel class of hybrid elements is proposed to alleviate the locking anomaly in non-uniform rational B-spline (NURBS)-based isogeometric analysis (IGA) using…
A Bayesian regularization-backpropagation neural network model for peeling computations
Saipraneeth Gouravaraju, Jyotindra Narayan, Roger A. Sauer +1
Bayesian regularization-backpropagation neural network (BR-BPNN) model is employed to predict some aspects of the gecko spatula peeling viz. the variation of the maximum normal and…
On the presence of a critical detachment angle in gecko spatula peeling -- A numerical investigation using an adhesive friction model
Saipraneeth Gouravaraju, Roger A. Sauer, Sachin Singh Gautam
A continuum-based computational contact model is employed to study coupled adhesion and friction in gecko spatulae. Nonlinear finite element analysis is carried out to simulate spa…
