Finite Element Training

ABOUT THE COURSE

Finite Element Analysis (FEA) is one of the most powerful tools used to assess the strength of engineering structures. This course is aimed at
engineers, of various disciplines, who intend to use the commercially available FEA Packages to analyse structures. Participants are assumed to have
knowledge of the basic principles of structural
mechanics. The syllabus will include: General overview of the technique, Finite element types (bars, beams, 2D, 3D, plate and shell elements) and their derivation via constant and higher order shape functions, pre and post processing, basic terminology, range of applications, basic introduction to materials modelling. Multidimensional FE modelling; Constitutive models in FE codes; FE model development; Assembly of stiffness matrices, loading and boundary conditions, material models, convergence; Advanced FE techniques; Modelling of 2D and 3D problems, buckling, non-linear analysis, advanced non-linear material models including failure and damage, explicit methods for dynamic problems; FE modelling accuracy, efficient mashing techniques, convergence and model verification.
WHO SHOULD ATTEND

Engineers and scientists involved in the design, operation and assessment of both onshore and offshore structures and their associated equipment. Personnel from oil companies, consultancy organisations, classification societies and certifying authorities will benefit from attending this course.
