The information processing device obtains a relation between a temperature amplitude of a fundamental frequency component of vibration for the object to be measured and a temperature amplitude of a second harmonic component of the vibration, performs fitting on the relation by using a first approximate line and a second approximate line, the first approximate line including a quadratic curve, the second approximate line including a quadratic curve, and obtains the fatigue limit stress of the object to be measured based on an intersection of the first approximate line and the second approximate line."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Fatigue limit stress specification system, fatigue limit stress specification device, and fatigue limit stress specification method","description":"A fatigue limit stress specification system includes: a vibration generator that repeatedly applies a load to an object to be measured; a temperature sensor that measures a change in temperature of th","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11275005","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
