Mechanics of MaterialsFor undergraduate Mechanics of Materials courses in Mechanical, Civil, and Aerospace Engineering departments. Hibbeler continues to be the most student friendly text on the market. The new edition offers a new four-color, photorealistic art program to help students better visualize difficult concepts. Hibbeler continues to have over 1/3 more examples than its competitors, Procedures for Analysis problem solving sections, and a simple, concise writing style. Each chapter is organized into well-defined units that offer instructors great flexibility in course emphasis. Hibbeler combines a fluid writing style, cohesive organization, outstanding illustrations, and dynamic use of exercises, examples, and free body diagrams to help prepare tomorrow's engineers. |

R. C. Hibbeler. 3.5 Strain Energy Az Ay σ σ Fig . 3-15 Ax As a material is deformed by an external loading , it tends to store energy internally throughout its volume . Since this energy is related to the strains in the material , it is ...
... Strain energy is caused by the internal work of the normal and shear stresses . It is always a positive quantity . • The strain energy can be related to the resultant internal loadings N , V , M , and T. • As the beam becomes longer , the ...
... strain energy in the differ- ential segment dx of the beam is equal to the external work , i.e. , dU ; = ( w dx ) ( y ) . Integrate this equation to obtain the total strain energy in the beam . El is constant . w dx 14-15 . The concrete ...
