Spline Finite Strip

Spline finite strip method is the basic theory to analyze the cold-bending formation. Based on principle of virtual work by spline finite strip method, energy model of strip element was established. The qualitative forming factors which are difficult to quantify, and the constraint conditions to form model were given into information description. Combing with specialist experience, solving task system of multi-Agent was established. By amending the Agent of knowledge containers and social relationships, every random factor influencing on forming quality effected objectively in the multi-Agent systems based on the changing environment. Then, the formation of dynamic task is solved. This work can provide theoretical guidance for complex design of steel in roll pass.

The Stability

Purpose This paper aims to analyze the stability of laminated shells subjected to axial loads or external pressure with considering various geometries and boundary conditions. The main aim of the present study is developing an efficient combined method which uses the advantages of different methods, such as finite element method (FEM) and isogeometric analysis (IGA), to achieve multipurpose targets. Two types of material including laminated composite and sandwich functionally graded material are considered. Design/methodology/approach A novel type of finite strip method called isogeometric B3-spline finite strip method (IG-SFSM) is used to solve the eigenvalue buckling problem. IG-SFSM uses B3-spline basis functions to interpolate the buckling displacements and mapping operations in the longitudinal direction of the strips, whereas the Lagrangian functions are used in transverse direction. The current presented IG-SFSM is formulated based on the degenerated shell method. Findings The buckling behavior of laminated shells is discussed by solving several examples corresponding to shells with various geometries, boundary conditions and material properties. The effects of mechanical and geometrical properties on critical loads of shells are investigated using the related results obtained by IG-SFSM. Originality/value This paper shows that the proposed IG-SFSM leads to the critical loads with an approved accuracy comparing with the same examples extracted from the literature. Moreover, it leads to a high level of convergence rate and low cost of solving the stability problems in comparison to the FEM.
