Adaptive Finite Element Simulation of Double-Diffusive Convection
Energies, 2023 Double-diffusive convection plays an important role in many physical phenomena of practical importance. However, the numerical simulation of these phenomena is challenging since fine meshes are often required to capture the flow physics.

Damage-based finite-element vertebroplasty simulations [PDF]
European Spine Journal, 2004 The objectives of this study were to quantify the efficacy of vertebroplasty according to: (1) damage and (2) cement quantity (fill) and modulus. Vertebral body damage was numerically simulated using a previously validated two-dimensional finite-element model coupled with an elasto-plastic modulus reduction (EPMR) scheme.

Finite Element Simulation of Blanking Process
International Islamic University Malaysia Engineering Journal, 2012 : The blanking process can be simulated by ABAQUS v 6.4 to select punch, die and press and ascertain punch wear and bur height. The experimental and the simulation results agree well with rising punch force up to the point of creation of crack. For a 2mm

Finite element modelling and experimental study of oblique soccer ball bounce [PDF]
, 2011 In this study, we develop a finite element model to examine the oblique soccer ball bounce. A careful simulation of the interaction between the ball membrane and air pressure in the ball makes the model more realistic than analytical models, and helps us

Finite element simulation [PDF]
, 1998 The Finite-Element formulation of Musical instruments has the advantage, that the definition of elements is very sophisticated. So we may define elements to be very small or to cover small sections of the geometry which is more difficult in the Finite-Difference formulation when not applying virtual points within the structure.

Modelling and finite element simulation of multi-sphere swimmers
Comptes Rendus. Mathématique, 2021 We propose a numerical method for the finite element simulation of micro-swimmers composed of several rigid bodies moving relatively to each other. Three distinct formulations are proposed to impose the relative velocities between the rigid bodies.
