Impact properties and water uptake behavior of old newspaper recycled fibers-reinforced polypropylene composites [PDF]

open access: yes, 2020
Natural fiber-reinforced thermoplastic composites can be an alternative to mineral fiber-based composites, especially when economic and environment concerns are included under the material selection criteria. In recent years, the literature has shown how

Impact Strength Of Glass And Glass Ceramic [PDF]

open access: yes, 2009
Strength of glass and glass ceramic was measured with a bar impact technique. High-speed movies show regions of tensile and compressive failure. The borosilicatc glass had a compressive strength of at least 2.2 GPa, and the glass ceramic at least 4 GPa ...

Depth of Cracking beneath Impact Craters: New Constraint for Impact Velocity [PDF]

open access: yes, 2002
Both small-scale impact craters in the laboratory and less than 5 km in diameter bowl-shaped craters on the Earth are strength (of rock) controlled. In the strength regime, crater volumes are nearly proportional to impactor kinetic energy.

The weakening relationship between the Impact Factor and papers' citations in the digital age [PDF]

open access: yes, 2012
Historically, papers have been physically bound to the journal in which they were published but in the electronic age papers are available individually, no longer tied to their respective journals.
