Chapter 6a – Plane Stress/Strain Equations
www.ce.memphis.eduChapter 6a – Plane Stress/Strain Equations Learning Objectives • To review basic concepts of plane stress and plane strain. • To derive the constant-strain triangle (CST) element stiffness matrix and equations. • To demonstrate how to determine the stiffness matrix and stresses for a constant strain element.
Chapter 3 Torsion - ncyu.edu.tw
web.ncyu.edu.tw٠Circular cross sections remain plane (do not warp) and perpendicular to the axis of the shaft. ٠Cross sections do not deform (there is no strain in the plane of the cross section). ٠The distances between cross sections do not change (the axial normal strain is zero). Each cross section rotates as a rigid entity about the axis of the shaft.
