Electrostatic charging is a complex phenomena and the degree to which it occurs is affected by a number of factors including contact surface properties of both materials coming into contact with each other, particle properties, the contact event (contact pressure, area, time, and frequency), and atmospheric conditions (21,22). Particle size, shape, surface nature, purity, roughness, and the properties of the powder and contact material... 

Positions of people, equipment, material, and their relationships to pre-contact, contact, and post-contact events. Include the position of the witness being interviewed. 

In tackling the no-contact events, the keyword is potential. What did the event have the capacity to do under slightly different circumstances The potential is what should determine which of these near miss incidents should be investigated as well as the level of the investigation. 

The next step is the determination of the corrosion rate of the depassivated material. In order to keep continuously a part of the immersed sample surface in an active state, the passive film has to be removed by mechanical contacts. It is thus necessary to select a rotation period, troi, which is small compared to treac so that the passive film has no time to regrow in between two successive contact events. It was proposed (Diomidis et al., 2009, 2010) to take the rotation period troi equal to ... 

A fracture system comprising a crack in a brittle material generated by a (sharp) elastic-plastic contact event and subsequently subjected to an applied stress is characterized by the fundamental equilibrium equation ... 

The key elements of the numerical scheme used in this study are its ability to incorporate the granular microstructure of the ceramic material, to simulate the spontaneous initiation, propagation and branching of intergranular cracks and subsequent fragmentation of the body, to account for inertial and finite kinematics effects and to capture the complex contact events taking place between the fragments. 

This kind of sensor can be manufactured at different levels, that is, fiber, yam, or coating. In particular, foams can be pressure sensitive thanks to an additional surface coating realized by means of conducting inks which can change their conductance during a contact event (Brady et al., 2005). 

Of fundamental interest is the relationship between the total charge transferred in a contacting event and the real contact area. Tt is, unfortunately, rather difficult to measure the actual contact area if the real contact area can be measured, then some anamolies can often be rationalized, particularly when it is recognized that polymers are viscoelastic materials.
