Abstract
For 6082-T6 aluminum alloy,series of systematic experiments and numerical simulations were carried out on the mechanical properties of the material,the stable bearing capacity of components under axial and eccentric compression,as well as the mechanical behavior of bending components.Additionally,a test database of domestic aluminum alloy was established,and the reliability levels of five design methods including Chinese,European and American standards,as well as DSM and CSM were evaluated.Lateral impact tests and numerical simulations were conducted on 6082-T6 aluminum alloy circular tubes and aluminum foam-filled composite tubes.A calculation method for the dynamic response of the tube was proposed and the prediction method on the deformation of the component under impact was established.Exploratory research was also carried out on ultra-large span aluminum alloy mage-grid structures,and a new type of joint and stability analysis of these structures was proposed.The research provides a basis and technical support for the application of 6082-T6 aluminum alloy members and structures in engineering,as well as for enhancing the load-bearing and anti-impact defense capabilities of structures.
