<正>Very high cycle fatigue(VHCF) behaviors of bridge steel(Q345) welded joints were investigated using an ultrasonic fatigue test system at room temperature wi
Time-delay efects on the dynamics of Li′enard type equation with one fast variable and one slow variable are investigated in the present paper.By using the met
Based on exact Green strain of spatial curved beam,the nonlinear strain-displacement relation for plane curved beam with varying curvature is derived.Instead of
In this investigation,a modeling procedure of a telescopic boom of cranes is developed using the absolute nodal coordinate formulation together with the sliding
An analytical study of the two degrees of freedom nonlinear dynamical system is presented.The internal motion of the system is separated and described by one fo
Optical full-field measurement methods are now widely applied in various domains. In general,the displacement fields can be directly obtained from the measureme
