Achieving the mechanical properties of steels after various manufacturing and heat treatment processes is significant and essential. In production lines, after producing the specific and standard samples, mechanical properties have been measured by destructive processes which cause waste of cost and time. In addition, destructive techniques cannot detect the miniscule changes made in mechanical...

in this study, the physical properties (size, mass, volume, density, geometric diameter, sphericity and friction coefficient on galvanized steel and wood surface) and some mechanical properties of flesh and skin tissue (modulus of elasticity, bioyield stress, yield strain and toughness) for small, medium and large melons of ghasri variety were determined. means comparison was done by duncan’s m...

The main goal of this research is to extract the full mechanical properties of stitch biax and triax composite materials which are necessary for finite element analysis, based on limited available experimental data and without performing full static characterization tests. Utilized experimental data are limited to elastic modulus of two 0o and 45o directions. Using presented technique and afore...

Combining the theories of politics of scale from political geography, security theory from international relations, and energy security theory, and putting the scale conversion of energy contention, geographical relationship and geo-structure in geo-setting, and the three properties of safety in consideration, this paper rebuilds a geo-energy security evaluation model and uses the model to quan...

Combined processing using different sensor types, i.e. for applications like change detection, requires a good geo-referencing. Furthermore the individual sensor properties have to be taken into account. SAR systems are side-looking and run-time systems. They suffer from occlusions and ambiguities especially in urban areas. Additionally layover and shadow effects disturb the geo-referencing of ...

The surface material at the Surveyor 5 site is granular and slightly cohesive. Spacecraft footpads plowed trenches in this material as the spacecraft slid during landing. For a compressible soil model, a static bearing capacity of 2.7 newtons/cm •' gave best agreement with the observations. Static firing of the vernier engines against the surface moved surface particles; a crater 20 cm in diame...

The mechanical response of PC12 neurites under tension is investigated using a microneedle technique. Elastic response, viscoelastic relaxation, and active contraction are observed. The mechanical model proposed by Dennerll et al. [J. Cell Biol. 109, 3073 (1989).10.1083/jcb.109.6.3073], which involves three mechanical devices--a stiff spring kappa coupled with a Voigt element that includes a le...
