Integration algorithms of elastoplasticity for ceramic powder compaction [PDF]
, 2014 Inelastic deformation of ceramic powders (and of a broad class of rock-like and granular materials), can be described with the yield function proposed by Bigoni and Piccolroaz (2004, Yield criteria for quasibrittle and frictional materials. Int.

Mapping snow depth return levels: smooth spatial modeling versus station interpolation [PDF]
Hydrology and Earth System Sciences, 2010 For adequate risk management in mountainous countries, hazard maps for extreme snow events are needed. This requires the computation of spatial estimates of return levels. In this article we use recent developments in extreme value theory and compare two
