Introduction Many materials had a spatially varying microstructure that led to spatial variation in elastic properties and thus a nonhomogeneous model should be established to meet the needs of describing the material properties.
Recently, authors were interested in the development of graded materials which had spatial property variations deliberately created to improve mechanical performance [1].
In this paper, a FEM model of the crankshaft was established to study the effect of the nonhomogeneous materials properties on the structure strength of the induction quenched crankshaft.
The distributed loads were applied to the connecting rod journal to simulate the explosion pressure.

The present study has been aimed to combine the advantages of the two single-phase materials, Al2O3 and ZrO2 while avoiding their disadvantages, by producing a mixed ceramic.
Introduction Alumina and zirconia ceramics have been successfully used as materials for joint endoprostheses.
The coupling of ZrO2 with Al2O3 components, used with varied results, is under debate, too. [3] Material and Methods The present study has been aimed at combining the advantages of the two single-phase materials, Al2O3 and ZrO2 while avoiding their disadvantages, by producing a mixed ceramic.
This high-strength, thermodynamically stable material is necessary for the manufacture of products that have so far been the domain of metallic materials alone.

The crack tip field in functionally graded piezoelectric materials (FGPMs) under mechanical and electrical loadings is studied.
Different from previous analyses, all material properties of the functionally graded piezoelectric materials are assumed to be linear function of y perpendicular to the crack.
Introduction Functionally graded piezoelectric materials (FGPMs) are composites with continuously varying properties that have significant advantages over discretely layered materials.
