Experimental and numerical investigation of residual stress stiffening influence on dynamic response of welded structures
(ASME, 2019-11-25)This paper presents the study of welding residual stress-stiffening effect on the dynamic responses and vibrational parameters of welded aluminum parts through an experimental modal analysis and Center Hole Drilling (CHD) ... -
Low-velocity impact and damage process of composite laminates
(SAGE Publications, 2002-04)Several important issues regarding damage simulation of composite laminates due to low velocity impact were investigated including contact law, damage initiation and the corresponding change of stiffness, and damping. ... -
Numerical comparison of negative damping bounds in a specified domain when the wave speed varies
(IEEE, 1992-06-24)The energy decay of a self-excited wave equation utt - c2 ¿ u - P(x)ut = 0 is studied where the wave speed c is greater than one, P(x) ¿ 0, and P(x) L¿(¿), ¿ ¿ ¿ Rn. Moreover, the relationship between two bounds for ... -
Stability of coupled strings vibration system due to different boundary conditions
(IEEE, 1993-06-02)We study the rate of convergence of a coupled wave systems under two different boundary conditions, energy absorbing in two ends for one and free or fixed boundary controls in two ends for the other one. We will observe ... -
