Failure analysis of an elbow tube fitting

Description: This article discusses elbow tube fitting. Abstract: Safe operation of machinery depends strongly on the design of the system and the employement of proper components and materials. Unique to fluid powered systems are the proper selection of hydraulic lines, fittings, and control valves. This paper describes the cause of fracture in an elbow tube fittings due to deficiencies in the dimensional design and materials selection. The investigation included metallography, fractography, hardness testi… more

Mechanical property enhancement of self-bonded natural fiber material via controlling cell wall plasticity and structure

Description: This article explores self-bonded natural fiber material (SNFM) as a promising alternative for plastic and wood owing to its abundant raw material resources and low environmental impact. In this study, a high-performance SNFM was developed by the comprehensive treatments for the plasticity and structure of fiber cell walls. The self-bonded mechanism for natural fiber materials was also discussed. The SNFM products showed excellent mechanical performance, which was superior to that of natural wo… more
