Authors Pelekasis N.A., Gaki A., Doinikov A., Tsamopoulos J.A. Abstract The translational velocities of two spherical gas bubbles oscillating in water, which is irradiated by a high-intensity acoustic wave field, are calculated. The two bubbles are assumed to be located far enough apart so that shape oscillations can be neglected. […]

Authors Talaslidis D.G., Manolis G.D., Paraskevopoulos E., Panagiotopoulos C., Pelekasis N., Tsamopoulos J.A. Abstract A modular analysis package is assembled for assessing risk in typical industrial structural units such as steel storage tanks, due to extreme transient loads that are produced either as a result of chemical explosions in the […]
Authors Dimakopoulos Y., Tsamopoulos J. Abstract We examine the transient displacement of viscoelastic fluids by a gas in straight cylindrical tubes of finite length. For the simulation of the processes, the mixed finite element method is combined with a quasi-elliptic grid generation scheme for discretizing the highly deforming domain of […]
Authors Foteinopoulou K., Mavrantzas V.G., Tsamopoulos J. Abstract Numerical results are presented concerning bubble growth in Newtonian and viscoelastic filaments undergoing stretching. In practice, such bubbles or cavities develop in materials (either in their bulk or at their interface with a substrate) such as the pressure sensitive adhesives. The problem […]
