Analysis of a Unilateral Contact Problem with Normal Compliance [PDF]

open access: yesAnnals of the West University of Timisoara: Mathematics and Computer Science, 2014
The paper deals with the study of a quasistatic unilateral contact problem between a nonlinear elastic body and a foundation. The contact is modelled with a normal compliance condition associated to unilateral constraint and the Coulomb's friction law ...

Low Left Atrial Compliance Contributes to the Clinical Recurrence of Atrial Fibrillation after Catheter Ablation in Patients with Structurally and Functionally Normal Heart. [PDF]

open access: yesPLoS ONE, 2015
Stiff left atrial (LA) syndrome was initially reported in post-cardiac surgery patients and known to be associated with low LA compliance. We investigated the physiological and clinical implications of LA compliance by estimating LA pulse pressure (LApp)

Variational analysis of a frictional contact problem with wear and damage

open access: yesMathematical Modelling and Analysis, 2021
We study a quasistatic problem describing the contact with friction and wear between a piezoelectric body and a moving foundation. The material is modeled by an electro-viscoelastic constitutive law with long memory and damage.

Unexpected pulmonary mechanics during positive pressure mechanical ventilation in fibrotic lung disease with concomitant flail chest

open access: yesRespiratory Medicine Case Reports, 2023
Understanding of pulmonary mechanics is essential to understanding mechanical ventilation. Typically, clinicians are mindful of peak and plateau pressures displayed on the ventilator and lung compliance, which is decreased in lung disease such as ...

A dynamic contact problem between elasto-viscoplastic piezoelectric bodies

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2014
We consider a dynamic contact problem with adhesion between two elastic-viscoplastic piezoelectric bodies. The contact is frictionless and is described with the normal compliance condition. We derive variational formulation for the model which is in

Effect of magnesium sulfate on oxygenation and lung mechanics in morbidly obese patients undergoing bariatric surgery: a prospective double-blind randomized clinical trial [PDF]

open access: yesKorean Journal of Anesthesiology, 2023
Background Respiratory mechanics are often significantly altered in morbidly obese patients and magnesium sulfate (MgSO4) is a promising agent for managing several respiratory disorders.

Linear versus nonlinear reliability-based topology optimization with application to bridge structures [PDF]

open access: yesE3S Web of Conferences, 2021
In general, two types of topology optimization models can be found in literature. The first type is called Deterministic Topology Optimization (DTO) leading to a single layout when considering a given design space.
