Failure in ductile sheet metal structures is usually caused by one, or a combination of, ductile tensile fractures, ductile shear fractures or localised instability. In this paper the failure characteristics of the high strength steel Docol 600DP are explored. The study includes both experimental and numerical sections. In the experimental sections, the fracture surface of the sheet subjected t...

The area underlain by the Barkerville Terrane has an important exploration and mining history dating from the discovery of placer gold on Keithley Creek in 1860. Placer gold production peaked in the 1860s, but continues at a modest scale to the present time. Lode gold production came mainly from the Wells mining camp, located near some of the richest placer streams in the district, between 1933...

The finite element simulation of forming processes or vehicle crash scenarios involves multiaxial loading conditions in general. Thereby, damage and failure ductile steel sheets is triggered by void growth under hydrostatic tensile elongation within a narrow band shear dominated loading. These different mechanisms are considered stress state dependent continuum model. initiation represented cri...

The fracture initiation in ductile materials is governed by the damaging process along the plastic loading path. A new damage plasticity model for ductile fracture is proposed. Experimental results show that fracture initiation in uncracked ductile solids is sensitive to the hydrostatic pressure and is dependent on the Lode angle. The damage plasticity model is established on a "cylindrical dec...

This paper studies the hydromechanical behavior of a slightly compacted mixture sand and clayey silt (30%/70%) under generalized stress state. The experimental study focused on analyzing yielding response shear strength at different states (characterized by intermediate principal parameter b, or Lode angle) initial total suctions (as-compacted state). For investigation, hollow cylinder apparatu...
