For engineering change, the opportunities offered by the use of new materials are important, and a possibility of integrating mechatronic components and systems into the existing products arises.
Smart items (electronics, software, materials) integrated into the existing product offer new features and capabilities to the user.
A very important point to engineering change is to apply a new design of materials and mechatronic systems to forming the base for increasing the effectiveness of this phenomena.

So the disqualified machining dimensions, material property are the main reasons for the fraction of this crankshaft.
The microstructure of the journal central section was tempered sorbite and many ferrolites, and it is shown that the segregation was existed heavily in the material, as shown in Fig. 5.
It can be seen that the chemical compositions of the material are within the specified range.
FEA Simulation With the development of science and technology, FEA is receiving more and more applications in engine.
(3) The microstructure and the non-metallic inclusions of the material don’t meet the specification; these will reduce the endurance bending strength of the material, so it aggravated the fatigue fracture process.

This volume of journal "Materials Science Forum" was collected by results of 19th International Symposium on Advances in Abrasive Technology (ISAAT 2016, Stockholm, Sweden, October 2-5, 2016) and intended to disseminate the recent advances in both conventional and nonconventional technologies of materials removal and covers many aspects of modern scientific and engineering practice in area of materials machining.
Topics include: grinding and polishing, abrasive fine-finishing, micro- and nanomachining, ultrasonic and laser machining, surface integrity and materials characterization, as well as other advanced cutting technologies and etc.
This book will be useful for academics and practicing engineers in advancement of the efficient materials removal technologies for modern mechanical engineering.
