Failure analysis and risk management of a collapsed large wind turbine tower

This paper presents a review of two-dimensional (2D) and three-dimensional (3D) finite element grinding models after 1995 and categorizes them by the scale of the modeling approach—either macro- or micro-scale. Macro-scale models consider the overall wheel–workpiece interaction while micro-scale models focus on the individual grain–workpiece interactions. Each model is discussed and the relevant boundary conditions, material constitutive treatments, and load inputs are compared. Future directions for finite element grinding modeling are then recommended and, based on the results of this review, synthesized current state-of-the-art macro- and micro-scale modeling approaches are presented.

Finite element modeling approaches in grinding

This paper gives a bibliographical review of the finite element methods applied to the analysis and simulation of welding processes The bibliography is an addendum to the finite element analysis and simulation of welding: a bibliography (1976–96) published in Modelling Simul Mater Sci Eng (1996) 4 501–33 The added bibliography at the end of this paper contains approximately 550 references to papers and conference proceedings on the subject that were published in 1996–2001 These are classified in the following categories: modelling of welding processes in general; modelling of specific welding processes; influence of geometrical parameters; heat transfer and fluid flow in welds; residual stresses and deformations in welds; fracture mechanics and welding; fatigue of welded structures; destructive and non-destructive evaluation of weldments and cracks; welded tubular joints, pipes and pressure vessels/components; welds in plates and other structures/components

Finite element modelling of temperature distribution in the cutting zone in turning processes with differently coated tools

A thorough understanding of the material removal process in cutting is essential in selecting the tool material and in design, and also in assuring consistent dimensional accuracy and surface integrity of the finished product. Tool wear in cutting process is produced by the contact and relative sliding between the cutting tool and the workpiece, and between the cutting tool and the chip under the extreme conditions of cutting area. This paper presents the information on development of study on theoretical analysis and numerical simulation of tool wear in all over the world. Hidden Markov models (HMMs) were introduced to estimate tool wear in cutting, which are strongly influenced by the cutting temperature, contact stresses, and relative strains at the interface. Finite element method (FEM) is a powerful tool to predict cutting process variables, which are difficult to obtain with experimental methods. The objective of this work focuses on the new development in predicting the tool wear evolution and tool life in orthogonal cutting with FEM simulations.
