Bi-penalty stabilized technique with predictor–corrector time scheme for contact-impact problems of elastic bars
(Elsevier, 2021-11)
This paper presents a stabilization technique for the finite element modelling of contact-impact problems of elastic bars via a bi-penalty method for enforcing contact constraints while employing an explicit predictor–corrector ...

Inverse mass matrix for isogeometric explicit transient analysis via the method of localized Lagrange multipliers
(John Wiley & Sons, 2019-03)
A variational framework is employed to generate inverse mass matrices for isogeometric analysis (IGA). As different dual bases impact not only accuracy but also computational overhead, several dual bases are extensively ...

Inverse mass matrix via the method of localized lagrange multipliers
(National Technical University of Athens, 2017-06)
An efficient method for generating the mass matrix inverse is presented, which can be tailored to improve the accuracy of target frequency ranges and/or wave contents. The present method bypasses the use of biorthogonal ...

Explicit multistep time integration for discontinuous elastic stress wave propagation in heterogeneous solids
(2019-05)
A multistep explicit time integration algorithm is presented for tracking the propagation of discontinuous stress waves in heterogeneous solids whose subdomain-to-subdomain critical time step ratios range from tens to ...

Inverse mass matrix via the method of localized Lagrange multipliers
(John Wiley & Sons, 2018-01)
An efficient method for generating the mass matrix inverse of structural dynamic problems is presented, which can be tailored to improve the accuracy of target frequency ranges and/or wave contents. The present method ...
