Modelling the Contact between the Rolling Elements and the .

In slewing bearings, a great number of contact pairs are present on the contact surfaces between the rolling elements and raceways of the bearing. Computations to determine the load of the individual rolling elements, taking into account the flexibility of the bearing ring, are most often carried out using the finite element method.

Finite Element Analysis of Large Diameter Bearings .

Analysis of large diameter bearings is complex process. The evaluation of change in contact angle due to applied load is vital in order to study the load carrying capacity of large diameter bearings. Analytical and Numerical procedures have been developed to calculate various design factors such as contact angle, contact stress and deformation.

A new numerical method for determining collapse load .

Determination of collapse load-carrying capacity of elasto-plastic material is very important in designing structure. The problem is commonly solved by elasto-plastic finite element method (FEM). In order to deal with material nonlinear problem involving strain softening problem effectively, a new numerical method-damped Newton method was proposed.
