A new MITC4+ shell element
We presented in Ko et al.(2016) an MITC4+ shell element that shows a much improved
convergence behavior when compared to the widely used MITC4 (Dvorkin and Bathe, 1984) …

Locking-free isogeometric discretizations of linear plane Timoshenko rods: LAS elements
We make use of linear plane curved Timoshenko rods as a model problem to study how to
overcome shear and membrane locking in NURBS-based discretizations. In this work, we …
