Stress / Strength

Stress/Strength Analysis - Structural/Mechanical Analysis of Components and Systems
Stress/Strength analysis method determines the probability of failure based on the probability of stress exceeding strength.
Calculation of Failure Probability (Unreliability) by:
? Distributions of Stress and Strength
? Variation information between Stress and Strength (Factor of Safety n and Variations)

Stress/Strength Analysis

Having distributions of Stress and Strength, we may calculate failure probability (Unreliability):

Unreliability Calculation

Having variation information between stress and strength (Factor of Safety n and Variations), we may also calculate the unreliability:
