  3. MMAE Seminar - Dr. Sayed Saghaian - Mechanical Behavior of Materials

Armour College of Engineering's Mechanical, Materials & Aerospace Engineering Department will welcome Dr. Sayed M. Saghaian, an Advanced Development Engineer at Fiat Chrysler Automobiles, on Friday, September 29th, to present his lecture, Mechanical Behavior of Materials.

Abstract

Mechanical properties of a material determine its behavior when subjected to mechanical loads. These properties include elastic modulus, ductility, and various measure of strength. Mechanical behavior of materials is important in design because the function and performance of a product depend on its capacity to resist deformation under the stresses encountered in service. In design, the usual objective is for the product and its components to withstand these stresses without significant change in geometry. This capability depends on properties such as elastics modulus and yield strength. In manufacturing, the objective is just the opposite where the stresses that exceed the yield strength of the materials must be applied to alter its shape.

Materials are frequently chosen for structural application because of their desirable combinations of mechanical characteristics. The present discussion is confined primarily to the mechanical behavior of metals. This lecture discusses the stress-strain behavior of materials and the related mechanical properties (Modulus of Elasticity, Yield Strength, Ductility), and also examines other important mechanical characteristics.

Biography

Sayed M. Saghaian was born in 1987 at Kentucky, USA. He has received his Ph.D. degree in Mechanical and Materials engineering from University of Kentucky in 2015. He is currently working as an Advanced Development Engineer at Fiat Chrysler Automobiles. The main responsibility at FCA is to develop light weighting solutions by using plastic and composite materials to improve the efficiency of the vehicles. His research during graduated study was concentrated mostly on characterization of mechanical and materials properties of advanced materials and to establish process-microstructure-property relationship in high temperature/high strength smart alloys.
