Analytical method for the kinetostatic analysis of the second-class RRR ASSUR Group allowing for friction in the kinematic pairs
(SciELO Brasil, 2010)
The calculation of forces in the kinematic pairs of mechanisms by inverse dynamics is usually performed without friction considerations -- In practice, when examination of articulated mechanisms takes into account friction, ...

(Springer Berlin Heidelberg, 2010-07-01)

A nonsmooth frictional contact formulation for multibody system dynamics
(John Wiley & Sons Ltd, 2020-08-07)
We present a new node-to-face frictional contact element for the simulation of the nonsmooth dynamics of systems composed of rigid and flexible bodies connected by kinematic joints. The equations of motion are integrated ...
Lagrangian systems with higher order constraints
(American Institute of Physics, 2007-05-31)
A class of mechanical systems subject to higher order constraints (i.e., constraints involving higher order derivatives of the position of the system) are studied. We call them higher order constrained systems (HOCSs). ...
FEA Structural Optimization Based on Metagraphs
(Springer Verlag, 2019-01-01)
Evolutionary Structural Optimization (ESO) seeks to mimic the form in which nature designs shapes. This paper focuses on shape carving triggered by environmental stimuli. In this realm, existing algorithms delete under - ...

Meso-scale response of concrete under high temperature based on coupled thermo-mechanical and pore-pressure interface modeling
(Pergamon-Elsevier Science Ltd, 2018-03)
This work proposes a meso-scale approach for modeling the failure behavior of concrete exposed at elevated temperature inducing thermal damage. The procedure accounts for a thermo-mechanical and pore-pressure based interface ...
Acoustics of partially saturated rocks: Theory and experiments
(Elsevier, 2015)
The presence of fluids in the pore space of rocks causes wave attenuation and dispersion by the mechanism broadly known as wave-induced fluid flow (WIFF). WIFF occurs as a seismic wave creates pressure gradients within the ...
