Geometry - A long plate of thickness t and depth D. The length is not defined because the plate is considered to be of infinite length. A circular hole of diameter d has its centre at the centre of the plate.
Loading - Uniformly distributed tensile load (w = 150 N/mm)
Material Properties - Young’s modulus (E = 80 kN/mm2) and Poisson’s ratio ( = 0.3)
Geometric Properties - Plate thickness (t = 4mm); Depth of plate (D = 75mm) and Diameter of hole (d = 42.5 mm)
Element type - 2D plane stress 4 and 8 noded quadrilateral elements.
Stress concentration, which is caused by the circular hole, will appear at the centre of the plate. Therefore, various points around the hole will exhibit an increased stress level higher than the nominal stress in other points of the plate.
After taking the decision of what length of plate to model, the size of the FE model is reduced even further by making use of the symmetry in the model.
Brief content specification: introduction to FEA, problem specification, methods, analysis, results, discussion / further work, conclusion
An overview of the key definitions and theorems of topology. It is based on the lectures and lecture notes of Professor Crainic.
