“…A leak is caused by direct attributes initiated by intrinsic attributes and reinforced by the external attributes. Joint leaks are caused by gasket degradation or excessive displacement of pipes [11]- [13]. The displacement starts from pipe deformation due to bending or thermal effects.…”

“…Interactions with the soil are the main source of external stress; the soil's contraction or expansion caused by temperature variations induces significant stress and causes pipes to deform or break [16], [28]. Furthermore, pipe deflection due to non-uniform ground settlement or groundwater fluctuations also produces bends and creates stress on pipes and joints [13], [38]. Impacts from tree roots were clearly explained by the higher failure rates with increasing wind speeds and storms in the Netherlands in et al [28].…”

The drinking water mains, mostly buried underground and stay there for decades, require proper maintenance to prevent failures. Among different kinds of material, polyvinyl chloride (PVC) has been widely used due to positive features such as high durability, corrosion resistance, low price, and easy installation. To the best of our knowledge, this is the first paper that reviews the inspection methods toward continuously monitoring the structural health of PVC drinking water mains. To understand which properties need inspecting, we first investigated the attributes that influence PVC pipe and joint failures. Then, we reviewed the methods that have already been applied or can inspect these influencing attributes. We categorized the prospects into five groups: sound wave, fiber optic sensing, hydraulic monitoring, multiple discrete sensors, and other inline methods. Finally, we discussed the possibility and challenges in implementing these methods into a continuous monitoring system of PVC water mains for early failure warning. The result, which includes active sound wave, fiber optic sensing, hydraulic vibration, multiple discrete sensors methods, can help future researchers select the appropriate methods to develop the continuous monitoring system for the PVC water mains.Index Terms-drinking water mains, PVC pipe, pipeline inspection, continuous monitoring, early failure warning, leak, pipe crack. I. INTRODUCTIONG RADUALLY, polyvinyl chloride (PVC) has become the dominant material in the Dutch drinking water mains due to its many advantages such as high durability, resistance to many chemicals, low price, and great flexibility [1]. Although more reliable than other pipes [2], PVC mains also become old

“…It is important to be aware of the bend radius size. If the bend radius is too short, the pipe may buckle (Rahman & Watkins, 2005). The radius of the pipe to be bent is taken as 1.5 D practically (Sandıkcı, 2012).…”

In heavy commercial vehicles, The parts that transfer the movement in the steering box to the wheels are called drag links. Drag links are bent in different geometries due to vehicle designs and other components in the steering system. Drag links are exposed to repeated tension and compression forces on the vehicle depending on the road conditions and the loads on the vehicle. In this study, static buckling forces and fatigue behavior of a drag link were determined according to different bending radii and the effect of bending radius on drag link life was investigated.
