The intention of shot peening is ultimately to alter the mechanical properties of a given surface. By hitting the surface with controlled shot the surface will deform plastically. Proper Instrumentation, nanoindentation, will play a vital factor in achieving reliable and intended results.
There is a new European regulation (10/2011) addressing plastic materials and components intended for food contact. It is important to understand this regulation to ensure compliance, thus protecting your company when it becomes effective. The new regulation applies to all unreinforced and reinforced plastics, including those that are reinforced with glass fibres. This presentation addresses glass reinforced plastics and the necessary changes that you should be aware of. To see more go to www.reinforcedplastics.com
Shot peening is a process by which a substrate is impacted with round metal, glass or ceramic beads, also known as shot, at a force intended to create plasticity on the surface. The characteristics present prior to and after the peening process provides vital information to better the understanding and control of the process. Among many others, surface roughness and dimple coverage area left by the shot, are of particular interest using a profilometer.
Microindentation hardness mapping has been widely used to assess the variation of mechanical properties across a large surface area. However, with the study of applications such as glass it is the crack initiation that is of particular interest. It is for this reason that acoustic emission can be used during the mapping of indents to not only map hardness but also map the crack initiation values over the surface area.
Dear friends,
Looking for a possible solution of a problem with external axial friction moment on a shear bolt.I tried to get literatures related with this type of combined loading,but not succeed much.If u can help me it would be great!
Space flight re-entry vehicles need to withstand heavy impact upon landing and it is critical for engineers to understand the effects on the vehicle and the crew to ensure the safety of the mission. In order to gain this insight, engineers need to be able to model both the space craft structure and the landing medium such as water, sand, clay, etc.
Mercury Marine outboards, engines, and drives are designed to withstand indoor impact testing (called “logstrike”) that simulates a collision with an underwater object. This test is comprised of an outboard or sterndrive device mounted on a mock boat that collides with a simulated log.
Paper transport is one of the areas under media handling methods where papers are transported by rollers through different path ways. The challenge in media handling is to transport the paper smoothly with out jam or in-plane deviation (paper skew). The smooth flow of paper is influenced by grade of paper, complexity of flow path, roller speed, roller pre-loads and significantly the roller material. It is also costly and difficult to develop a physical flow path testing.
