Evaluation of Disc Cutter Performance in Rock Cutting Process Using 3D Finite Element Method

Today, numerical simulation can be used as a suitable tool to measure large quantities that are very expensive and, in some cases, impossible to measure. One of the important issues in predicting rock mass boreability in excavation with full face tunnel boring machines is estimating the discchr('39')s forces for rock cutting. For this purpose, the linear cutting test is  employed. However, limi...

Finite Element Analysis of Hardened Steel Cutting

Hard machining, as attractive replacement for many rough and finish grinding operation, generates high cutting forces and temperature that enhance tool wear when act together. Therefore, the tool geometry and machining parameters have to be carefully optimized for a given material. Because of high cost and time consuming experimental work up-to-date advanced software for modeling and simulation...

Stress Distribution in Four Restorative Methods in Endodontically Treated Maxillary Premolar: A 3D Finite Element Analysis

Introduction: the Restoration of endodontically treated teeth is critical, and the Awareness of stresses developed by oblique and vertical forces in restorative methods take a great role in treatment plans. Due to the anatomical shape and inherent form of the stress distribution premolars, could be lost by fractures. Some fractures such as vertical fracture which is probable in...

A New Restructured Shaded Pole Induction Motor- 3D Finite Element Analysis and Experimental Verification

Shaded pole induction motors, despite the simplicity and low cost, are difficult to analyze particularly in the equivalent circuit methods, due to the asymmetric structure, saturation, harmonics, inaccurate estimation of leakage inductances and skew. Hence, 3D numerical methods could be very useful in the design and optimization stage. This paper presents the 3D transient finite element analysi...
