MDP: N161- Stress Analysis Fall Stress Analysis -MDP N161 Transverse Shear (Chapter 7- sec. 7.1-sec.7.3) Instructor: Dr. Chahinaz A.R.Saleh Lecture 7

MDP: N161- Stress Analysis Fall Objective

MDP: N161- Stress Analysis Fall Introduction

MDP: N161- Stress Analysis Fall Equilibrium implies that shear stress exists in pairs, i.e. the transverse shear stress is associated with longitudinal shear stress.

MDP: N161- Stress Analysis Fall  The value of the shear stress at the upper and lower boundaries are zero since they are adjacent to free surfaces.

MDP: N161- Stress Analysis Fall Longitudinal shear stress prevents sliding in case (b) for bonded boards

MDP: N161- Stress Analysis Fall The Shear Formula

MDP: N161- Stress Analysis Fall Assumption: The shear stress is constant along the thickness t at any distance y measured from the neutral axis
