Modelling of material cutting with a material microstructure-level (MML) model [PDF]

open access: yes, 2013
In this research work a material microstructure-level cutting model (MML cutting model) is presented. The crystal plasticity theory is adopted for modeling the cutting of the titanium alloy Ti–6Al–4V in orthogonal case.

A constitutive model with damage for high temperature superalloys [PDF]

open access: yes
A unified constitutive model is searched for that is applicable for high temperature superalloys used in modern gas turbines. Two unified inelastic state variable constitutive models were evaluated for use with the damage parameter proposed by Kachanov ...

The role of local space charge concentrations in producing branched tree structures [PDF]

open access: yes
Electrical trees are branched damage structures produced in polymeric insulation subject to high divergent fields. The density of branching ranges from a sparse form like a tree in winter to a dense compact form like a bush.

Export Processing Zones and Environmental Policy [PDF]

open access: yes
This paper investigates the relation between an export processing zone and a pollution quota in a small country. The model suppose that the pollution target is implemented with a marketable permit system, and the government sets the quota to maximize ...
