PLASTIC DEFORMATION BACKGROUND

Background Unit: Plastic Deformation and Stress-Strain Curves Introduction In the last unit we studied the elastic response of materials to externally applied loads. All the loads applied were well below the elastic limit of the materials so no permanent deformation occurred in the sample.

Cracks and Crack Control in Concrete Structures

www.pci.org

CAUSES OF CRACKING Concrete can crack due to a number of causes. Some of the most significant causes are discussed in detail. Tensile Strength of Concrete The tensile strength of concrete is a widely scattering quantity. Cracking oc-curs when tensile stresses exceed the tensile strength of concrete. Therefore, to control concrete cracking, the ...

recent two years, just about 20 percent are concrete dams and remaining 80 percent are embankment dams. It is thus readily recognized that construction of embankment dams is a recent world-wide trend in place of concrete dams. Two major distinct features and advantages are noticed for the construction of embankment dams. 1.
