Figure 14 compares the thickness strains measured in HET, DENT, and uniaxial tensile specimens. For all the investigated AHSS grades, the values of thinning measured in HET specimens (TTS HET) are within the range of thickness strain measurements from DENT specimens (ε 3f i DENT and ε p 3f DENT).
WebThe fracture toughness for a material at a specific thickness can be approximated as: where t is the material thickness, A k and B k are material constants, and t 0 is the plane-strain thickness at critical loading as calculated by: where … WebSteels with a higher strength have a greater risk especially when the thickness is greater than 25mm. Aluminium treated steels with low sulphur contents (<0.005%) will have a low risk. Steel suppliers can provide plate …
Web25 Nov 2024 · To confirm the distributions of the transverse strain and thickness strain of the neck region, strain distributions were extracted for the martensitic steel and dual-phase steel as shown in Fig. 5. Both the transverse strain and thickness strain exhibited changes in strain distribution at engineering strain after UTS, similar to the trend of equivalent strain … WebA Forming Limit Curve (FLC) is a map of strains indicating the onset of critical through-thickness necking for different linear strain paths. The FLC is dependent on the metal grade and the specific methods used in its creation. When paired with the strains generated during forming of an engineered part, the associated Forming Limit Diagram (FLD) provides …
