Upscaling the Strength Domain of Heterogeneous Cohesive‐Frictional Materials via a General FFT‐Based Limit Analysis Approach

International Journal for Numerical Methods in Engineering, Volume 127, Issue 12, 30 June 2026.
ABSTRACT Limit analysis and yield design provide a well‐defined mathematical framework for upscaling the strength properties of heterogeneous materials. These techniques can be incorporated into an FFT‐based computational micromechanics framework to evaluate the strength of heterogeneous materials, based on images of their microstructure.

Paper 17: Dynamic Characteristics of a Hydrostatic Thrust Bearing

, 1963
An earlier comprehensive application of the Navier-Stokes equations to the problem of the oscillatory loading of hydrostatic thrust bearings has been linearized, and shown experimentally to be true for ratios of vibration amplitude to oil film thickness
