In Chapters 7, 9, 10 and 11 we determined stress distributions produced separately by axial load, bending moment ... of elastic failure in Section 14.10 we shall examine states of stress and strain at ...

The hypothesis used in developing the stress and strain in the shaft is that all points on a cross-section of the shaft experience the same angle of twist. The angle of twist for a section of length L ...

The answer is “yes”. Such materials are known as “auxetic materials”. From above, we see than an auxetic material will expand in the transverse directions for a tensile axial load. Consider the ...
