Engineering Materials: Properties and Classification

In this article we will discuss about the properties and classification of engineering materials used in industries. Properties of Materials: Material selection should be based mainly upon the properties of material. The designer must decide the properties required of a material for a part under design and then weight the properties of candidate material. There are literally hundreds of properties [...]

List of Metals and their Alloys | Material Engineering

Here is a list of metals and their alloys. An alloy is a substance that has metallic properties and is composed of two or more chemical elements, of which, at least one is a metal. Basically, alloying is done to give strength to metal as the alloying element occupies interstitial space, which create compressive and tensile strength depending on the [...]

Scheduling Procedures for Production | Production Management

There are several scheduling procedures in use. We take the following scheduling example: 1. Shortest Processing Time (SPT) Procedure: A schedule obtained by sequencing jobs for production in non-decreasing order of processing times is called a shortest processing time (SPT) schedule. This schedule minimizes mean flow time F̅. In addition, the SPT rule also minimizes mean lateness and means waiting [...]
