Role of Fatigue and Creep in Structural Damage: A Comprehensive Review
Abstract: Fatigue and creep are two critical degradation mechanisms that significantly influence the structural integrity and longevity of engineering materials. These phenomena arise due to different loading and environmental conditions but often coexist in various industrial applications, leading to severe material degradation over time. Fatigue primarily results from cyclic loading, where repeated stress variations induce microstructural damage and crack initiation, ultimately causing catastrophic failure. Conversely, creep occurs under sustained stress at …

Long-Term Effects of Feeding High-Lignin Forage to Ruminants: Implications for Productivity, Health, and Sustainability
Abstract: The long-term feeding of high-lignin forage to ruminants can significantly impact various aspects of animal performance, health, and environmental sustainability. Lignin, a complex phenolic compound present in plant cell walls, is indigestible by rumen microbes, leading to reduced fiber digestibility and decreased nutrient utilization. Over time, feeding ruminants with forages high in lignin results in a decline in voluntary dry matter intake (DMI), inefficient energy and protein absorption, and suboptimal …
