FINITE ELEMENT PREDICTION OF DUCTILE FRACTURE IN AUTOMOTIVE PANEL FORMING: COMPARISON BETWEEN FLD AND LEMAITRE DAMAGE MODELS
In sheet metal forming processes with complex strain paths, a part is subjected to large plastic deformation. This severe plastic deformation leads to high plastic strain localization zones and subsequent accumulation of those strains. Then internal and superficial micro-defects and in other words ductile damage is created. This damage causes quality problems such as fracture. Therefore, design...
متن کاملAn Experimental and Numerical Study of Forming Limit Diagram of Low Carbon Steel Sheets
The forming limit diagram (FLD) is probably the most common representation of sheet metal formability and can be defined as the locus of the principal planar strains where failure is most likely to occur. Low carbon steel sheets have many applications in industries, especially in automotive parts, therefore it is necessary to study the formability of these steel sheets. In this paper, FLDs, wer...
متن کاملDynamic Necking of Rods at High Strain Rates
The dynamic necking instability of a rod of a non-linear viscoplastic material as formed in shaped charges is investigated. A two-dimensional linear Lagrangian perturbation method leads to a single fourth order partial differential equation with time-dependent coefficients. The growth of disturbancies depends of the interplay between the stabilizing inertial and viscous effects, and the destabi...
متن کاملInfluence of the Loading and Strain Rates on the Strength Properties and Formability of Higher-strength Sheet
Cold formability of material is influenced by all factors participating in the forming process. The crucial factors include the sheet material, whose formability is the most often evaluated according to its yield point, tensile strength and their ratio, elongation, uniform deformation, their combination, etc. [1]. In the forming process, these material characteristics are significantly influenc...
متن کاملPrediction of forming limit curves (FLD, MSFLD and FLSD) and necking time for SS304L sheet using finite element method and ductile fracture criteria
Forming limit curves are used as a parameter in finite element analysis to control the material's level of formability. In this research, forming limit diagram (FLD) of SS304L sheet was obtained by ABAQUSfinite element software. In practice, the experimental determination of a forming limit curve is a very time-consuming procedure which requires special and expensive equipment. Forming limit di...
