Experimental study on compressive behavior of PE-ECC under impact load

چکیده
Compared with polyvinyl alcohol-engineered cementitious composites (PVA-ECC), engineered containing polyethylene fibers (PE-ECC) has captured the attention of researchers because lower cost. Nevertheless, there is a limited amount research that focuses on their dynamic behavior. Thus, specimens different water binder ratios were tested by split Hopkinson pressure bar (SHPB) to unveil compressive behavior PE-ECC. The behaviors analyzed based tests, including failure modes, stress-strain curves, strength, peak strain, and toughness. result shows PE-ECC excellent ductility, long post-peak descending part in relations. Furthermore, sensitivity analysis reveals strain rate most crucial factor directly affects toughness monotonic fashion.

There have been some experimental tests on hollow curved-steel struts with thin-walled square sections, in order to investigate their general behavior, particularly their capacity for bearing differing loads. One set of square tubes are cold-formed into segments of circular arcs with curvature radii, equal to 4000 mm. Different lengths of curved struts are fabricated so as to cover a practical ...

Actual applications of the energy absorbers showed that actual loads are not applied in the form of pure axial compression, pure bending or pure torsion. In reality, an energy absorber component may be subjected to combined loading of compression, bending and torsion. A number of previous articles have investigated the behavior of energy absorbers under oblique loading. In such cases, the obliq...
