Sincemuch engineering practice is cross-disciplinary, this allows students to learn about materialsfrom other than just their own disciplinary perspective. This course is integrated with thestatics/strength and math courses they are taking at the same time. Faculty teaching thesedifferent courses meet regularly to make sure that the integration between them is working well.For example, this integration allows us to discuss mechanical behavior of materials, whilerelying on the statics/strength course for their mechanics background.Connected with this new materials lecture course are two revised lab courses: a civilengineering materials

The tedium of iterative calculations is placed on the algorithms, allowing thestudents to concentrate on the parameters appropriate to their specific design application.I. IntroductionThe design of a mechanical component typically involves an iterative approach to determine anappropriate set of parameters that satisfy the requirements and constraints associated with thespecific design problem. For example, in the design of an extension or compression spring for aparticular application, the engineer must select the following parameters: 1. Type of spring to be designed 2.

Many universities offer graduatelevel courses on materials science. These courses provide fundamental knowledge on thestructure, mechanics and physics behind advanced materials. The emphasis on these courses is“science”, not “engineering”. Students graduating with a materials science degree acquire theknowledge on the fundamentals of materials science and very little on materials engineering.

The course combines statics and strength of materials at an introductory level forall students regardless of major (this will turn out to be a very significant point that must bekept in mind). Typically, the concepts of stress in objects caused by torsion, bending, andcombined loading are among the most difficult for students to grasp.
