Springback Compensation in Hydroformed closed section parts
For the continued growth of tube-hydroforming, better methods for creating and validating springback compensation are essential. Upcoming vehicle programs forecast increasing use of Advanced...
Material Matters: Sheet metal plasticity visualized (part 2 of 2)
As already discussed in Sheet metal plasticity visualized (part one) there are four main components needed to model the plastic deformation of sheet metals:...
Material Matters: Sheet metal plasticity visualized (part 1 of 2)
As already discussed in the post “Constitutive modeling of sheet metal” there are four main components needed to model the plastic deformation of sheet...
Material Matters: modeling of sheet metal- the “known unknowns”
Modeling of sheet metal stamping can raise many questions regarding the validity of engineering decisions based on finite element analysis. Knowing only the grade...
The Stamping System
A recurring theme on this blog, so far, has been sources of variation in production that might not be apparent to engineers when defining,...
Parameters for Hot Forming and Quenching: Engineering and Design
Have you ever defined a hot forming process virtually?
How do you determine which design and process parameters are required for the production...
Why is springback worse for HSS and AHSS?
It seems that you cannot have a discussion about High Strength Steel (HSS) and Advanced High Strength Steel (AHSS) without springback shortly becoming the...
Material Matters: as-shipped vs. as-engineered material
Are all coils created equal? Various coils have potentially different mechanical properties. Source image attribution: www.terexmphs.com
In tryout and production the engineering “boundary conditions” used...
