Study on the stress and deformation of a diaphragm compressor cylinder head under extreme conditions

open access: yesIOP Conference Series: Materials Science and Engineering, 2019
When a high-pressure diaphragm compressor applied in the hydrogen refueling station, the structure strength of the cylinder head are one of the most important evaluation criteria to guarantee the reliability and efficiency of the diaphragm compressor ...

Simulation Analysis and Parameter Optimization of Residual Film Pickup Process Based on Finite Element Method

open access: yesAgriculture
The extended duration of mulching in Xinjiang cotton fields leads to a significant decline in the tensile strength of plastic film. When recycling is in operation, the soil and the spring teeth of the machinery used can easily cause secondary damage and ...

Strain bursts in plastically deforming Molybdenum micro- and nanopillars [PDF]

open access: yes, 2008
Plastic deformation of micron and sub-micron scale specimens is characterized by intermittent sequences of large strain bursts (dislocation avalanches) which are separated by regions of near-elastic loading.

Field investigation of deformation characteristics and stress mobilisation of a soil slope [PDF]

open access: yes, 2015
Stress mobilisation and deformation of a slope are important for engineers to carry out reliable design of retaining systems. However, most case histories reported mainly on the response of pore-water pressure (PWP), whereas knowledge about the stress ...

Interseismic strain accumulation: Spin-up, cycle invariance, and irregular rupture sequences [PDF]

open access: yes, 2006
Using models of infinite length strike-slip faults in an elastic layer above linear viscoelastic regions, we investigate interseismic deformation. In the models we investigate, interseismic strain accumulation on mature faults is the result of the ...
