Smart Traction Control Systems for Electric Vehicles Using Acoustic Road-type Estimation
, 2019 The application of traction control systems (TCS) for electric vehicles (EV) has great potential due to easy implementation of torque control with direct-drive motors. However, the control system usually requires road-tire friction and slip-ratio values,

Finite element analyses of fatigue crack growth under small scale yielding conditions modelled with a cyclic cohesive zone approach [PDF]
, 2013 Mode I fatigue crack growth is modelled and investigated with a cohesive zone approach. A 2D finite element boundary layer model under plane strain and small scale yielding conditions is used to generate fatigue crack growth rate curves ...

Improved recovery of admissible stress in domain decomposition methods - application to heterogeneous structures and new error bounds for FETI-DP [PDF]
, 2016 This paper investigates the question of the building of admissible stress field in a substructured context. More precisely we analyze the special role played by multiple points.

Weakly Enforced Boundary Conditions for the NURBS-Based Finite Cell Method [PDF]
, 2012 In this paper, we present a variationally consistent formulation for the weak enforcement of essential boundary conditions as an extension to the finite cell method, a fictitious domain method of higher order. The absence of boundary fitted elements in

Analysis of delamination growth with discontinuous solid-like shell elements [PDF]
, 2004 Delamination is one of the most important failure mechanisms in laminates. Normally, it is modelled using interface elements. These elements are placed between two layers that are modelled with continuum elements. The interface elements are equipped with

Bond Graph Based Stability Analysis of a Railway Traction System [PDF]
, 2005 This paper emphasises the interest of the Bond Graph approach for analysis and system design of heterogeneous and multi-field devices. In particular, the local stability analysis of non linear systems can be directly derived from the linearised Causal ...
