A Structural Nonlinear Analysis Workspace (SNAW) based on meshless methods

On the application of meshfree methods to the nonlinear dynamics of multibody systems

“…The relative deformation of the lower node of the segment is shown in Figure 7. 26. The response gives very similar results in the horizontal deformation to the ones presented for the 2D meshfree plane strain model.…”

“…The requirements for its design are motivated for the need of sharing as much functions as possible between both approaches, in order to make a fair comparison between existing FEM techniques and the proposed meshfree methods applications. Its requirements and functionality are inspired in the SNAW code [26], which was written for the application of the RKPM method in the field of structural mechanics. It also has some similarities from the user's perspective to the multibody script language HOTINT…”

Calculation of Strain Energy Density Function Using Ogden Model and Mooney–Rivlin Model Based on Biaxial Elongation Experiments of Silicone Rubber

“…CAE analysis has become indispensable for the development and design of new products [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 ]. Abaqus and Marc are well-known analytical software programs, but recently Ansys and Nastran have also become popular.…”

jNURBS: An object-oriented, symbolic framework for integrated, meshless analysis and optimal design

“…It can be used to analyze two-dimensional heat transfer and plate natural vibration problems on multiply connected curved polygonal domains. SNAW (Structural Nonlinear Analysis Workspace), developed by Hardee et al [12], is applicable to hyperelastic and elasto-plastic materials, using explicit and implicit time integrations, and involving rigid-toflexible-body frictional contact conditions. These tools are designed to solve limited, pre-defined types of problems.…”
