Tearing stress is related to both shear stress and bearing stress, as it is a failure mechanism that typically occurs in notches due to shear forces. A tear-out commonly happens when a notch is placed to close to the edge of a material. Basically, what happens is a portion of the plate, right after the notch, gets torn out due to excessive ...

Definition of pulverization. "Pulverization" (comminution, crushing, grinding) is the process of applying an external force to a (solid) material of a certain size to destroy it and reduce it into pieces that are smaller than the original size. Pulverization has long been done for many materials, including ore, glass, ceramics, grains ...

Shear stress exists when two parts of a material tend to slide across each other in any typical plane of shear upon application of force parallel to that plane. Torsion is a variation of pure shear in which a structural member is twisted. Torsional forces produce a rotational motion about the longitudinal axis of one end of the member relative ...

It is defined as force per unit area which is associated with stretching and denoted by σ. It is defined as the amount of tensile stress a material can withstand before breaking and is denoted by s. The formula is: σ = F/A. Where, σ is the tensile stress. F is the force acting. A is the area. The formula is: s = P/a.

If this parameter is omitted, the compressive yield stress depends only on the inelastic strain, the strain rate, and, possibly, on temperature. See "Specifying field variable dependence" in "Material data definition," Section 9.1.2 of the ABAQUS Analysis User's Manual, for more information.

Definition of crushing strength. i. The resistance that a rock offers to vertical pressure placed upon it. It is measured by applying graduated pressure to a cube, 1 in (2.54 cm) square, of the rock tested. A crushing strength of 4,000 lb means that a cubic inch of the rock withstands pressure to 4,000 lb (111 kg/cm 3 ) before crushing.

The desired concrete crushing failures shown in Figs. 1.24 and 1.25 can only be achieved if IC, CDC and PE debonding can be prevented from occurring before the design load to cause concrete crushing. However, this may not always be possible; in which case, it may be necessary to design for either IC or CDC debonding to occur at the …
