8. STRENGTH OF SOILS AND ROCKS - University of Melbourne
people.eng.unimelb.edu.aushear stress is the shear strength of the soil for the particular value of the normal force N or normal stress (N/A) applied to the soil, where A is the cross sectional area of the soil sample. Fig. 8.8 shows that a dense sand has a greater shear strength than a loose sand and this strength is reached at a smaller value of the displacement.
CE 405: Design of Steel Structures – Prof. Dr. A. Varma
www.egr.msu.edu- The shear strength of the bolts depends on whether threads are included or excluded from the shear planes. If threads are included in the shear planes then the strength is lower. - We will always assume that threads are included in the shear plane, therefore less strength to be conservative. • We will look at specifications J3.7 – J3.9 later.

Fastener Loads for Plywood – Screws
www.grabberman.comb) Fastener-critical joints are characterized by a shear failure of the screw shank. As shown in Figure 1, once localized crushing of the wood has occurred, resistance to fastener-head embedment into the metal causes the screw to become a shear specimen and joint behav-ior is dependent upon the shear strength of the fastener.
