2006 Third International Symposium on 3D Data Processing, Visualization, and Transmission (3DPVT'06)  
This paper extends the idea of classification schemes for static surface curvature into the temporal domain.  ...  We seek to identify regions in sequences of depth data that exhibit variations in shape change, and to characterise the nature of the deformation.  ...  In so doing, we maintain that this produces a compact representation of dynamics for qualitative characterisation of deforming surfaces.  ...

Formation of Planetesimals and Accretion of the Terrestrial Planets [chapter]

Stuart J. Weidenschilling
2000 Space Sciences Series of ISSI  
As each layer of particles is deposited on the surface, it loads and deforms the underlying material such that subsequent layers are applied to an object that has a non-zero stress field.  ...  This stress field is qualitatively different from that of a non-accreted body determined using the usual elasticity analysis and is illustrated by comparing the failure mechanisms of the two bodies.  ...  As each layer of particles is deposited on the surface, it loads and deforms the underlying material such that subsequent layers are applied to an object that has a non-zero stress field.  ...
