FEM – Simulation – Calculation Competence As an expert in structural calculations of buried pipes, manholes, reservoirs and containers, we offer a wide range of designing services for different materials. Experience in finite element analysis (FEA) since 1997 State of the art FEA software, such as NX Nastran Close collaboration with numerous engineering companies and consultants, as well as pipe, manhole and container manufacturers in Germany and worldwide Performance Modeling and meshing Finite element analysis – linear and non-linear Determination of traffic loads Elaboration of solutions and optimization measures Verification and interpretation of the solution Pre-consultation for the verification of structural calculations Software for structural analysis of buried pipes, jacking pipes, liners and manholes Custom software development Tangential manhole Manhole cone Designing services for structural calculation of buried pipes Tube banks (close bedding of two or more pipes, which influence each other and therefore do not correspond to calculations covered by common standards) Cable outlets and cable protection tubes (also underneath the rails of Deutsche Bahn) Pipeline routes underneath airport runways Extensive know-how in the field of sewer rehabilitation Relining for any profiles Host pipe conditions (ARZ) I, II and III Recalculation of existing pipes considering the present conditions of pipe installations Lining Manhole calculations Special shaped parts (tangential connections, fins, etc.) Consideration of mounting parts, openings and outlets Cones made of any materials, among others plastics with and without reinforcing fins, corrugations, symmetrical and asymmetrical Arbitrary load positions Reservoir and container calculations Reservoirs with demanding geometries; reinforced with fins, multiply sheeted Silos, tanks and bunkers Wall thickness optimization You are interested in an individual FEA solution? Please contact us, we will gladly assist you. See the back page for contact information. Standards We conduct necessary verifications in accordance to the current standards and guidelines. A comparative analysis by different standards may be conducted. Silo Pre-processing Processing Post-processing The goals are to develop an appropriate finite element mesh, assign suitable material properties and apply the boundary conditions in the form of restrains and loads. The equations are assembled into matrix form and are solved numerically. It is time for the analysis engineer to examine and interpret the solution. Following steps characterize the processing phase: The expetise of the engineer is crucial for this phase: Crucial parameters and steps: Geometry Material Type of the applied finite elements Meshing Geometric boundary conditions (displacements, restrains) Static boundary conditions (loads) Stiffness matrix calculation Load vectors calculation Equations assembly of the stiffness matrix, load vectors and displacement vectors of the system Solving the generated system of linear equations for the displacement vectors Creating a report Creating the report is a conclusion of the finite element analysis. Among others, the report should contain following items: Project data (definition, sketches, plans, soil analyses, existing documentation) Literature (standards, guidelines) Scope of work (calculation model, boundary conditions, load combinations, type of analysis) Graphic presentation of the examined parameters (stresses, strains, displacements etc.) Necessary static verifications (stability, buckling, usability) Possible modification suggestions IngSoft GmbH Landgrabenstr. 94 90443 Nuremberg Germany Tel: +49 (911) 430879-305 Fax: +49 (911) 430879-29 E-mail: Web: [email protected] www.ingsoft.de Version: 2014-01-22 Subterranean reservoir Investigating the plausibility of the solution Verifying the numerical accuracy of the solution Examining the quantities of interest Evaluating the analyzed model Creating a report
