A segmentation-free isogeometric extended mortar contact method [PDF]
, 2018 This paper presents a new isogeometric mortar contact formulation based on an extended finite element interpolation to capture physical pressure discontinuities at the contact boundary. The so called two-half-pass algorithm is employed, which leads to an

Mortars and plasters—how to manage mortars and plasters conservation [PDF]
Archaeological and Anthropological Sciences, 2021 AbstractThe use of mortars and plasters has been widespread in many cultures for thousands of years and these materials are found in the vast majority of built cultural heritage. They play a crucial role in the preservation of immovable heritage and must be taken into great consideration when conserving historical buildings.

On torque computation in electric machine simulation by harmonic mortar methods [PDF]
Journal of Mathematics in Industry, January 2022, 2021 The use of trigonometric polynomials as Lagrange multipliers in the harmonic mortar method enables an efficient and elegant treatment of relative motion in the stator-rotor coupling of electric machine simulation. Explicit formulas for the torque computation are derived by energetic considerations, and their realization by harmonic mortar finite ...
