ATLAS of yield surfaces for strongly textured FCC polycrystals
Experimental study on the formability of AA6016 sheets pre-strained by rolling
Modelling of Cold Metal Transfer Welding Process Using SPH
Experimental detection of forming limit strains on samples with multiple local necks
Sheet metal formability is traditionally described by the forming limit curve (FLC). Experimental FLCs are obtained by performing formability tests and determining failure strains. The strains are usually measured either by etching a grid on the sheet surface or by digital image correlation (DIC...
Density-consistent Initialization of SPH on a Regular Cartesian Grid: Comparative Numerical Study of 10 Smoothing Kernels in 1, 2 and 3 Dimensions
Smoothed particle hydrodynamics (SPH) simulations are often initialized on a regular Cartesian grid. Ten SPH kernels were analyzed numerically with respect to their ability to correctly reproduce a uniform density distribution. Three types of kernels were identified. The number of neighboring...
SPH based modelling of oxide and oxide film formation in gravity die castings
Gravity die casting is an important casting process which has the capability of making complicated, high-integrity components for e.g. the automotive industry. Oxides and oxide films formed during filling affect the cast product quality. The Smoothed particle hydrodynamics (SPH) method is...
Experimental detection of the onset of local necking in an aluminium sheet
Determination of Ductile Fracture Parameters of a Dual-Phase Steel by Optical Measurements
Marciniak–Kuczynski and Nakajima tests of the dual-phase steel Docol 600DL (www.ssab.com/) have been carried out for a range of stress-states spanning from uniaxial tension to equi-biaxial tension. The deformation histories of the specimens have been recorded by digital images, and the displacement...
