Opis

Your ticket to excelling in mechanics of materials With roots in physics and mathematics, engineering mechanics is the basis of all the mechanical sciences: civil engineering, materials science and engineering, mechanical engineering, and aeronautical and aerospace engineering. Tracking a typical undergraduate course, Mechanics of Materials For Dummies gives you a thorough introduction to this foundational subject. You'll get clear, plain-English explanations of all the topics covered, including principles of equilibrium, geometric compatibility, and material behavior; stress and its relation to force and movement; strain and its relation to displacement; elasticity and plasticity; fatigue and fracture; failure modes; application to simple engineering structures, and more.

• Tracks to a course that is a prerequisite for most engineering majors
• Covers key mechanics concepts, summaries of useful equations, and helpful tips

From geometric principles to solving complex equations, Mechanics of Materials For Dummies is an invaluable resource for engineering students

Your ticket to excelling in mechanics of materials

Mechanics of Materials For Dummies gives you plain–English explanations of all the topics you′ll encounter in a typical undergraduate course, including principles of equilibrium, geometric compatibility, and material behavior; stress and its relation to force and movement; strain and its relation to displacement; and methods for calculating deformations and indeterminate systems.

• Brush up on basics get a quick refresher on math and units, a brief review of essential statics topics, and an easy–to–follow introduction to mechanics of materials

• Sharpen your skills find out which skills you need to master, including section property calculations, internal force diagrams, and how to locate the centroid of an area

• Stop stressing get the 411 on the basic types of stress, grasp the difference between average stress and stress at a point, and learn to transform stresses to find principal values and angles

• Strain for more discover how objects deform in response to strain, how you compute maximum and minimum strain values, and how to determine strain orientation within an object

• Compute displacements explore different ways to compute deformations of objects under loads for both statically determinate and indeterminate systems

Open the book and find:

• How to use mechanics to understand material behavior

• Methods for calculating stresses and strains
