The methodology involves full automation of model generation, submission, termination and processing with object-oriented scripting, illustrated using code and pseudocode fragments. This paper illustrates a computational strategy to deal with both issues that may help researchers establish sets of RRD parameters for other important shell systems with greater confidence and accuracy. finite element code Abaqus 6.14-2 and an explicit dynamic analysis method was. Handling so many nonlinear finite element models is time-consuming and the quantities of data generated can be overwhelming. The pounders impact on the soil surface and the resulting vibration on the. length, radius to thickness ratio, imperfection amplitude, linear strain hardening modulus). Their partial algebraic characterisations required thousands of finite element calculations to be performed across a four-dimensional parameter hyperspace (i.e. The systems that have received by far the most research attention for RRD are that of a cylindrical shell under uniform axial compression and uniform bending. metals yield surface by using notched strips, 144 FE models where constructed and analysed using the software Abaqus/CAE 6.14-1 (Dassault Systmes, 2014). The points that you selected to define the wire are listed in the Point Pairs table. The Create Wire Feature dialog box reappears. When you have finished selecting points, click Done in the prompt area. The formidable challenge now is to establish these parameters and resistances for the most important shell geometries and load cases. As you select points, Abaqus/CAE displays a representation of the completed point-to-point wire based on your current selections highlighted in red. The method achieves this by reformulating the outcomes of a vast programme of parametric FE calculations in terms of six algebraic parameters and two resistances, each representing a physical aspect of the shell's behaviour.

The new Reference Resistance Design (RRD) method, recently developed by Rotter, for the manual dimensioning of metal shell structures effectively permits an analyst working with only a calculator or spreadsheet to take full advantage of the realism and accuracy of an advanced nonlinear finite element (FE) calculation.
