Advances and Applications in Mechanical Fatigue and Life Assessment

Dear Colleagues,

This Special Issue is dedicated to exploring the latest developments, cutting-edge research, and real-world applications in the mechanical fatigue and life assessment of materials and structures. This Special Issue aims to bring together leading researchers, practitioners, and professionals to present and discuss novel methodologies, technologies, and case studies that enhance our understanding of the fatigue behavior, damage mechanisms, and life prediction of components under cyclic loading.

Fatigue and life assessment are crucial for ensuring the safety, reliability, and durability of mechanical components across various industries, including automotive, aerospace, energy, civil and industrial infrastructure. With the growing complexity of modern materials and structural designs, it is essential to develop new techniques and models to more accurately predict fatigue life and extend the service life of critical components.

Contributions that offer innovative solutions, experimental findings, theoretical advancements, and practical applications in the field of mechanical fatigue and life assessment are encouraged.

This Special Issue will cover, but is not limited to, the following topics:

• Experimental Methods in Fatigue Testing: novel testing techniques, high-cycle and low-cycle fatigue, multi-axial fatigue, and accelerated fatigue testing.
• Fatigue Damage Mechanisms: microscopic and macroscopic analyses of crack initiation, propagation, and coalescence in metals, composites, and polymers.
• Fatigue Life Prediction Models: advancements in computational models, empirical approaches, and machine learning-based life prediction methods.
• Probabilistic and Statistical Fatigue Approaches: uncertainty quantification, reliability analysis, and probabilistic fatigue life estimation methods.
• Environmental Effects on Fatigue: impact of temperature, corrosion, humidity, and other environmental factors on fatigue performance.
• Advanced Materials for Fatigue Resistance: fatigue behavior of advanced materials, such as high-strength alloys, fiber-reinforced composites, ceramics, and smart materials.
• Fatigue in Additive Manufacturing (AM): assessment of fatigue properties of AM components, post-processing effects, and defect-related fatigue behavior.
• Application of Fracture Mechanics in Fatigue: use of fracture mechanics principles for fatigue life extension, crack growth rate modeling, and damage tolerance assessment.
• Structural Health Monitoring and Fatigue Prognosis: integration of sensors, non-destructive evaluation (NDE), and data analytics for real-time fatigue assessment and life monitoring.
• Fatigue Design and Optimization in Engineering Systems: case studies and methodologies for fatigue design in aerospace, automotive, civil engineering, and power generation industries.
