Experimental and numerical investigation of the fatigue

With the rapid development of computer technology and advanced numerical techniques, more details, especially the characterization of crack growth, can be determined. For example, Hu et al . [ 20 ] used LS-DYNA to study the rock fragmentation mechanisms when cut by a cutter and concluded that there are three fracture modes of rock breaking: forward slip, no slip and backward slip.

Experimental and numerical characterization of a full

2016/12/1Steady-state simulations with multiple reference frames were conducted for each case using a pseudo-transient, coupled pressure-velocity solver. A rotating reference frame was applied within the turbine runner domain, which transformed flow from an unsteady inertial frame to a steady non-inertial frame with the inclusion of the centrifugal and Coriolis forces into the transport equations.

A Theoretical and Experimental Study of the Steady State

Formulas are derived for calculating the steady state saturation profile and pressure profile resulting from the end effect. A numerical integration is required to obtain the results. Two dimensionless numbers containing various parameters of the system are introduced, which, along with the viscosity ratio and the fractional flow of one component, characterize the system.

For a first setup omitting the geometrical complexity of the experimental model and only including the blade passage, results highlight that the steady-state blade loading is not predicted correctly. With a second computational setup including the cascade's detailed geometry, the relevant physics of the experiment are captured and the prediction accuracy is improved.

Experimental Characterization and Numerical Modeling

The test apparatus provided good results for steady-state or dynamic shear flows. However, this setup introduced strain hardening at larger strains because of an imposed steady shear, and it could not capture the effect of fiber orientation because in the Rheometric dynamic spectrometer machine, the relative motion is introduced by the rotation between the top and the bottom layers.
