What is critical in stress intensity?
Stress intensity is related to product of stress and flaw size for materials. If stress is increased to critical, this results in catastrophic failure. The critical stress intensity factor KIc is a property of the material. KIc = Strength x sqrt(flaw) x geometry factor
What is the relationship between Vickers Hardness and yield strength?
HV = 2.9 * Y Where HV - Vickers hardness Y - Yiekd stress in KG/mm2
What is the relationship between strength of an earthquake and how often it occurs?
Friction is overcome when the accumulating stress has enough force to ... About 90% of all earthquakes occur at a depth between 0 and 100 kilometers.

What is strength coefficient?
Strength coefficient is a parameter used in materials science to quantify the relationship between stress and strain in a material. It represents the ability of a material to withstand deformation before reaching its breaking point. The higher the strength coefficient, the stronger the material is under load.
What is Stress reduction factor in UG excavations?
The stress reduction factor is a product of the relationship between the Unconfined compressive strength of a rock and the sigma 1, or principal stress field in that area. The higher the value, the more likely the rock is to deform when placed under load.
What is CISD?
Critical Incident Stress Debriefing. Critical Incident stress Defusing.
Which of these explains the relationship between stress and performance?
Yerkes-Dodson law
What depends on the strength of an earthquake?
We determine the scaling relationships between earthquake stress drop and recurrence.
Is yield strength and proof stress same?
Yes it is the same. Offset Yield strength = 0.2% Proof Stress
What is the difference between yield strength and tensile strength?
Yield strength is the maximum stress a material can withstand without undergoing permanent deformation, while tensile strength is the maximum stress a material can withstand before breaking. In other words, yield strength represents the point at which a material changes from elastic deformation to plastic deformation, while tensile strength represents the maximum stress a material can handle before rupturing.
Difference between yield stress and yield strength?
Stress is a measure of the load applied to a sample relative to a cross sectional area of the sample. Strength is a quantification of the samples ability to carry a load. The terms "yield strength" and "yield stress" of a material are usually used interchangeably (correct or not). It is the stress which will just cause the material to plastically deform. If a material yields at 30,000 psi, the yield stress is 30,000 psi. If the part in question has a cross sectional area of 2 square inches, the strength at yield would be 60,000 pounds, but usually we just say the yield strength is 30,000 psi.
