A contact‐stabilized Newmark method for dynamical contact problems [PDF]
International Journal for Numerical Methods in Engineering, 2007 AbstractThe numerical integration of dynamical contact problems often leads to instabilities at contact boundaries caused by the non‐penetration condition between bodies in contact. Even an energy dissipative modification (see, e.g. (Comp. Meth. Appl. Mech. Eng. 1999; 180:1–26)), which discretizes the non‐penetration constraints implicitly, is not able

Arthritis Care &Research, EarlyView.Objective Although the definition of a gout flare is well established, the state of gout flare resolution has not yet been defined. This study aimed to explore patients’ experiences and perceptions of gout flare resolution. Methods Semistructured interviews were conducted with 24 people with gout, guided by open‐ended questions exploring their ...

Shakedown analysis for rolling and sliding contact problems [PDF]
, 2006 There is a range of problems where repeated rolling or sliding contact occurs. For such problems shakedown and limit analyses provides significant advantages over other forms of analysis when a global understanding of deformation behaviour is required ...

3D CONTACT PROBLEM ON INTERACTION BETWEEN FLEXIBLE WEDGE AND TWO PUNCHES UNDER FRICTION
Advanced Engineering Research, 2012 The spatial contact problem for the flexible wedge is investigated in the quasi-static formulation when two identical elliptic rigid punches are symmetrically impressed into one face of the wedge under friction. The other wedge face is stress-free.

The Physically Nonlinear Analysis of Circular Plate on Deformable Foundation
The Baltic Journal of Road and Bridge Engineering, 2011 A circular reinforced concrete plate on deformable foundation is investigated. The foundation is composed of three layers of soil which are defined as isotropically nonlinear materials with variable physical properties. The reinforced plate is treated as
