The expression for working out the total surface area of a cylinder is 2Ï€\(r\)² + 2Ï€\(rh\). \(r\) is the radius of the circular cross-section and \(h\) is the height of the cylinder.
The finite element method is used to simulate the elastic-plastic contact process of the cylinder. The influence of the load and radius of the cylinder model on the contact deformation and the contact ...
