Analysis of bend tests on polystyrene bead s

Expanded polystyrene (EPS) bead s tend to fracture when bent. Their indentation yield stress is low and there can be crushing at the loading points of 3-point bend tests. Such crushing can be prevented by using a beam of high span:depth ratio, and a large loading cylinder radius. An indentation yielding analysis confirms that EPS beams ...

Melted plastic

it may be polystyrene, which melts at a fairly low temperature. It did not catch fire as oxygen was excluded by the safe. Take a small sliver of the plastic and holding it in forceps light it with a match. If it burns with a very smoky, very pale yellow flame and the smell of the fumes from it remind you of the two part plastic used to repair
