Topic 13: Safety, Reliability and Integrity Mangement Processes and the Human Factor effect

Throughout History Man has experienced alot of severe and fatal incidences that could have been averted or most assuredly minimized if certain actions were taken or decision making processes where in place.

Hydrogel Hardness Using Nanoindentation

Hydrogel is known for its super absorbency of water allowing for a close resemblance in flexibility as natural tissue. This close resemblance has made Hydrogel a common choice not only in biomaterials, but also electronics, environment and consumer good application such as contact lens. The use and diversity in application have each their own unique needs and requirements. One such requirement will be known and controlled mechanical properties using nanoindentation.

Fracture Resistance of Silicon With Nano Scratch Testing

Scratch testing, using nano loads, has become widely used for the study of adhesion strength and marring resistance of thin films and coatings. This same test can also be used to study fracture behavior on brittle substrates similar to a marring resistance test approach. This can provide an in-depth observation of failure on delicate substrate materials at precisely controlled and recorded loads.

Nano Puncture Resistance Using Nanoindentation

Traditional Puncture Tests are typically used to determine the penetration characteristics of a wide range of protective material such as films, foils or membrane. It is widely used in food and medical industries on applications ranging from food packaging to rubber gloves and needles. The test is preformed like that of a compressive test. A probe, with multiple tip selection, uses increasing load until material is penetrated and load is recorded at failure.

Profilometers using Low Coherence Interferometry used by NASA to measures thickness

Using a fiber-based optical profilometer NASA measures the thickness of liquid nitrogen in cryogenic chambers at its Propulsion Systems lab because these profilometers use fiber-based probes which can withstands the extreme environment, can be located hundreds of meters away from the interferometer and fit in the tight chamber which standard full-field profilometers with a human operator could not. The signal quality stays constant over the distance.

Dear friends,

I have a question which I posted in BLOGS section a week or so back. But I have no reply / comment  from any reader of the blog.

So I am re-posting the same in this section ( FORUM) .

The query is as below ;

Renewable Power And Sunlight Energy - Thin-Film Solar Panel Products

As technology constantly advances there are many new green technologies released each day that can help us improve our energy efficiency. One such technology is the "Thin-Film Solar Panel." How are thin-film solar panels being utilized by consumers today? How do they compare against traditional photovoltaic (PV) panels?

Shot Peen Hardness With Nanoindentation

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.

FREE WEBINAR Food and Drinking Water Contact EU Regulations for Plastic Composites – How to be Prepared

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

Shot Peened Surface Characterization Using 3D Profilometry

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 Mapping With Acoustic Emission On Glass

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.

help friction+shear

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!
