We examined three united atom models in light of their description of polyolefin dynamics and investigated the relative influence of various potentials on the resulting dynamics. Results were compared with a collection of experimental data on polyethylene, poly(ethylene-alt-propylene), polypropylene, and head-to-head polypropylene, including quasielastic neutron scattering measurements that we ...

Combining fiber with concrete mixes has become essential and its widespread use improves the strength of structural elements. This research conducted an experiment into performance flat slabs without a square opening using four types (hooked-end, straight, corrugated steel polyolefin fiber) to gain better understanding how variance type shape effects flexural behaviors two-way slabs. The test p...

In this research, the structural behavior of reinforced concrete brackets cast with containing different types fibers was studied. Seven samples corbels were and tested. One specimen without fiber as a reference, other made six at constant volume fraction (1% total volume). The used in research two materials: steel polyolefin. polyolefin fiber, five remaining samples, used. Straight, crimped, t...

Polyethylene and polypropylene plant owners have experienced a volatile business environment in recent years. Prices have fluctuated dramatically and operating margins have echoed this volatility. For many plants, the number of different polymer grades produced has increased and customers have become more demanding with respect to product quality. Developments in advanced automation and informa...
