: Many curves illustrate the effects of critical variables such as temperature, humidity, surface hardening, frequency, and environmental conditions.
: Software like SOLIDWORKS Simulation explicitly references the Atlas of Fatigue Curves as a primary source for its S-N material database.
The is a definitive engineering reference published by ASM International . Edited by Howard E. Boyer, this 518-page volume consolidates over 500 fatigue curves for a vast range of industrial ferrous and nonferrous alloys into a single, comprehensive source. Core Content and Scope
: It includes standard S-N curves (Stress vs. Number of cycles), crack growth-rate curves, and comparative charts showing fatigue strengths across different alloys.
: Beyond raw data, the text provides a thorough explanation of fatigue testing methodology and how to accurately interpret test results. Practical Applications
: Analysts use these independent curves to compare real-world failures against standardized empirical data to determine if a design met its expected endurance limit.
