Abstract: This paper presents a compact and easily accepted continuous model for the elasticplastic contact of a sphere and a flat, including the relationships of load and contact area versus displacement and the relationship between ...

Abstract: This paper presents a cubic model for the sphere–flat elastic–plastic contact without adhesion. In the cubic model, the applied load and the contact area are described by the cubic polynomial functions of the displacement ...

Abstract: Low-ductility steel concentrically braced frames (CBFs) are widely used in buildings as a lateral resistance system in seismic regions around the world due to their high stiffness and strength. Steel CBF buildings have ...

Abstract: Many structures service in complex environments where multiple environmental factors (MEFs) coexist, and the coupling effects of MEFs often aggravate structural damage, thus increasing the risk of structural collapse and ...

Abstract: In this study, weldability of ultrasonic welding of 4-mm-thick fiber carbon/nylon 66 composite in lap configuration was investigated. Ultrasonic welding tests were performed, and the weld appearance, microstructure, and ...

Abstract: Large deformation analyses of structures are of great importance to the evaluation of structural performance under extreme environmental loads, but currently available methods are time-consuming because of the requirement ...
