Understanding of progressive failure in view of …

A series of single particle tests revealed that there are three types of failure mode; split failure, shear failure and compressive failure, depending on the number of contact points and the relative magnitude of their contact forces. From the one- dimensional compression tests, it was observed that so-called pre-consolidation pressure is corresponding to 50 % of accumulated crushing ratio and ...

APPLICATION OF ACOUSTIC EMISSION ON CRUSHING …

During the crushing test, two piezoelectric sensors with a bandwidth between 10 kHz and 1 MHz record the acoustic emission signals. The first AE sensor (AE 1), which links to channel 1 of the AE acquisition system, is fixed within the steel base plate, just below the particle at a depth of about 1 cm by means of a mechanical system that ensures a constant holding force (figure 3). The second ...

What is Single Particle ICP-MS? - TOFWERK

Single particle analysis using ICP-MS with quadrupole or sector-field mass analyzers is limited to simple systems – single-element metal- or oxide-particles – because these mass analyzers can only record the signal of one or two isotopes during the short duration of the particle detection event. In contrast, time-of-flight mass analyzers, such as that used in the TOFWERK icpTOF, can record ...

Single Event Effects - NASA

Single Event Effects (SEEs) are caused by a single, energetic particle, and can take on many forms. Single Event Upsets (SEUs) are soft errors, and non-destructive. They normally appear as transient pulses in logic or support circuitry, or as bitflips in memory cells or registers. Several types of hard errors, potentially destructive, can appear: Single Event Latchup (SEL) results in a high ...

SoloVPE Application Note for Gold Particle Testing

Gold Particle Testing (GPT) is the most precise user‐conducted integrity test on the market. It serves to reconfirm filter quality (pore size distribution) after filtration. In each test, a solution of colloidal gold particles, similar in size to the target viruses, is introduced into the filter. The gold particles are then filtered out of solution by the membrane during the course of the ...
