Abstract: Bidirectional evolutionary structural optimization (BESO) method has been successfully applied for a wide range of topology optimization problems. In this paper, the BESO method is further extended to the optimal design ...

Abstract: An implicit numerical integration algorithm is presented for the unified yield criterion, which could encompass most other yield criteria. The modification matrix, which is used to convert the continuum tangent modular ...

Abstract: The primary objective of this study is to investigate whether simplified blast loading together with a pier-bent model could be employed to reveal the main damage mechanisms of typical highway bridges subjected to blast ...

Abstract: Multicell tubal structures have generated increasing interest in engineering design for their excellent energy-absorbing characteristics when crushed through severe plastic deformation. To make more efficient use of the ...

Abstract: In calibrating model parameters, it is important to include the model discrepancy term in order to capture missing physics in simulation, which can result from numerical, measurement, and modeling errors. Ignoring the ...

Abstract: The dynamic failure characteristics and fracture process of brittle materials such as rock involves a complex crack propagation process, the underlying mechanics of which is not yet fully understood. At present, the ...

Abstract: Subsurface drip irrigation systems with water and fertilizer-aerated irrigation technology have helped improve crop yield and quality and are receiving increasing attention in the field of agricultural efficient irrigation. ...
