Uniaxial-stress induced phase transitions in [001]c-poled 0.955Pb(Zn1/3Nb2/3)O3-0.045PbTiO3

, 2007
First-order, rhombohedral to orthorhombic, stress-induced phase transitions have been evidenced by bulk charge-stress measurements and X-ray diffraction derived lattice strain measurements in [001]c-poled PZN-4.5PT.

Pre-fatigue influence on quasi-static tensile properties of Ti-6Al-4V in thin-sheet form [PDF]

, 2010
The response of engineering structures to loads is most often assessed without taking possible damage of the used material(s) into account. However, it has already been proved that a preceding cyclic loading and the alteration of the microstructure it ...

A Modified Eyring Equation for Modeling Yield and Flow Stresses of Metals at Strain Rates Ranging from 10−5 to 5 × 104 s−1

Advances in Materials Science and Engineering, 2015
In several industrial applications, metallic structures are facing impact loads. Therefore, there is an important need for developing constitutive equations which take into account the strain rate sensitivity of their mechanical properties.

Architecture of the sperm whale forehead facilitates ramming combat [PDF]

PeerJ, 2016
Herman Melville’s novel Moby Dick was inspired by historical instances in which large sperm whales (Physeter macrocephalus L.) sank 19th century whaling ships by ramming them with their foreheads.
