The element COS will depend on the type of element being used in the analysis, with surface elements ( ) by definition having the 3 direction out of plane of the surface, and beam elements ( ) having the 3 direction along the beam length. Orthotropic material properties are often used when modelling composite parts, as they have different stiffness in two orthogonal directions. ![]() x,y,z for the global but 1,2,3 for the element system.įor orthotropic materials, the element COS is used to define the properties. The element COS is generated automatically by the FEA solver and will often use notation different to the global system, e.g. Displacements at each node are calculated in the global COS ( ) and then used to find the element results, which are transformed to the element COS. Deformations, for example, may be more useful if displayed in a cylindrical COS for a column vessel, with the magnitudes shown in radial, axial and circumferential direction rather than in x, y and z direction.Ī local COS can be Cartesian, cylindrical or spherical. This video course presents general theory and use of finite element procedures. Results from analyses can be displayed in the global or the local COS, depending on the result in question. For example, a pipe that is supported by a clamp can be constrained only in the radial direction by using a local cylindrical COS. Finite element analysis (FEA) is a computerised method for predicting how a product reacts to real-world forces, vibration, heat, fluid flow and other. The use of FEA software begins with a computer-aided design (CAD) model that represents the physical parts being simulated as well as knowledge of the material properties and the applied loads and constraints. For example, when using a pie-cut ( ) symmetry model ( ), a local COS is used to define to symmetry planes of the pie-cut to apply the symmetry boundary condition.Ī local COS can be used to define any loads or constraints. Engineers and scientists use finite element analysis (FEA) software to build predictive computational models of real-world scenarios. The global COS in FEA is always the Cartesian ( ) COS, as all matrix calculations (stiffness, mass and damping) are done using this system.Ī local COS can then be used when it is advantageous. These activities are included in other services such as designs and audits.In FEA, different coordinate systems (COS) are used depending on the application. Limit state analysis to limit state-based codes such is SANS 10162-1 (in PROKON).Durability analysis which incorporates different fatigue models At Mechanical Piping Design we offer one of the best outsourcing Finite Element Analysis Services often referred as FEA by many in the. ![]()
