EN380: Naval Materials Science and Engineering

Catalog Description

EN380: Naval Materials Science and Engineering (3-0-3).

This course addresses the optimal use of materials in ocean systems with emphasis on corrosion prevention, fracture mechanics, and basic materials science.

Textbook

Callister and Rethwisch,, Material Science and Engineering: An Introduction , John Wiley and Sons, Inc., 8 th Edition, 2009.

Goals

  1. Demonstrate a basic understanding of mechanical properties of materials commonly used in marine applications, including strength, toughness, and hardness, as well as failure mechanisms of fracture, fatigue and creep.
  2. Demonstrate a basic understanding of metals and metal alloys commonly used in marine applications, including low carbon steels, alloy steels, tool steels, stainless steels, aluminum alloys, copper alloys, nickel alloys, and titanium alloys, including composition, physical and mechanical properties, fabrication, uses, and nomenclature.
  3. Demonstrate a basic understanding of phase transformation and heat treatment of metals and metal alloys, including basic metallurgical changes and effects on physical and mechanical properties.
  4. Demonstrate a basic understanding of corrosion in marine applications, including the nature of corrosion, corrosion prediction and measurement techniques, and corrosion control techniques.
  5. Demonstrate a basic understanding of composites commonly used in marine applications, including fiber-reinforced polymer (FRP) composites, concrete, and wood, including composition, physical and mechanical properties, fabrication, uses, and nomenclature.

Computer Usage

The students are required to make extensive use of the capabilities of their spreadsheet program for this course. Advanced features such as conditional logic, table lookup, intrinsic functions, and optimization are introduced and utilized. The students are required to develop spreadsheets for finding the section modulus of an entire midship section of a ship. The students are also encouraged to use their spreadsheet program to solve the design equations in a systematic form so that they can try different combinations of variables in order to do some basic optimization of their design.

Validation

Midshipmen studying abroad may be eligible to earn credit for this course.  This must be approved by the Course Coordinator and the Midshipman's Academic Adviser.  To be considered for validation:

  1. Read Marine Environment and Seawater Properties
  2. Read Corrosion Basics
