Abstract: This paper develops a method for dealing with the stress minimization of continuum structures based on the bidirectional evolutionary structural optimization (BESO) method. The modified p-norm approach has been used to ...

Abstract: Serious injuries and costly damages caused by excavators hitting underground utilities are constantly in the headlines of the news media. The accidents sometimes result in the death of one or more persons. Thus, excavation ...

Abstract: During tunnel excavation, stress redistribution is caused by disturbance of the surrounding rock; when the stress exceeds the strength of rock mass, the surrounding rock enters the postpeak deformation stage and then ...

Abstract: This paper proposes a method for topology optimization of periodic structures on dynamic problems by using an improved bidirectional evolutionary structural optimization (BESO) technique. Frequency optimization and ...

Abstract: A rational approach to the mechanical design of wheel rims as a typical periodic structure is presented in the current work. With novel application of the latest bidirectional evolutionary ...

Abstract: Internal waves close to the seafloor of abyssal oceans are the key energy suppliers driving near-bottom mixing and the upwelling branches of meridional overturning circulation, but their spatiotemporal variability and ...
