  • At the instigation of the Iron and Steel Federation, the late Bernard Godfrey began work in 1952 on the first edition of the Steel Designers’ Manual.As principal author he worked on the manuscript almost continuously for a period of two years. On many Friday evenings he would meet with his co-authors, Charles Gray, Lewis Kent and W.E. Mitchell to review progress and resolve outstanding technical problems. A remarkable book emerged.

  • This research project was motivated by the possibility of using fracture mechanics to assist in optimizing gear design. The primary goal is to develop a state-of-the-art capability for modeling three-dimensional crack propagation in gears using boundary element method, finite element method, and fracture mechanics. It is being conducted by a grant between Cornell University and the NASA-Glenn Research Center (formerly known as Lewis Research Center).

  • This is mainly applicable for short-lived devices where very large overloads may occur at low cycles. Typical examples include the elements of control systems in mechanical devices. A fatigue failure mostly begins at a local discontinuity and when the stress at the discontinuity exceeds elastic limit there is plastic strain. The cyclic plastic strain is responsible for crack propagation and fracture. Experiments have been carried out with reversed loading and

  • Tài liệu tham khảo giáo trình nhôm trong thiết kế xây dựng bằng tiếng anh - Chương 12 Fatigue 12.1 GENERAL DESCRIPTION It is well known that seemingly ductile metal components can fail in a brittle manner at a low load, far below their static strength, when this load is applied many times. Aluminium is more prone to this problem than steel. The phenomenon, known as fatigue, results from the presence of localized details or irregularities in zones carrying tensile stress, especially at welds....
