A deterministic model of impact noise transmission through structural connections based on modal analysis
(2011-01-17)
Article
Open AccessVibration transmission through structural connections is modelled in a deterministic way by means of modal analysis. This model is used first to study the effect of elastic joints across the floor in the transmission of ... -
A new bipenalty formulation for ensuring time step stability in time domain computational dynamics

The bipenalty method for arbitrary multipoint constraints
(John Wiley & Sons, 2013-02-03)
Article
Open AccessIn finite element (FE) analysis, traditional penalty methods impose constraints by adding virtual stiffness to the FE system. In dynamics, this can decrease the critical time step of the system when conditionally stable ... -
The effects of element shape on the critical time step in explicit time integrators for elasto-dynamics
(John Wiley & Sons, 2015-03-16)
Article
Open AccessIn this paper, the effects of element shape on the critical time step are investigated. The common rule-of-thumb, used in practice, is that the critical time step is set by the shortest distance within an element divided ...
