3 topics across all disciplines.
Sheet metal bending and springback
Why a flat blank is never the sum of the flange lengths, what the neutral axis and K-factor actually are, and why a stronger steel springs back further and has to be overbent to finish straight.
Deep drawing and stamping
How a flat blank becomes a body panel, what the forming limit diagram is really telling you, why blank holder force sits between wrinkling and splitting, and what draw beads are for.
Designing sheet metal parts
The rules that decide whether a sheet metal part can be made cheaply — minimum flange and hole spacing, relief notches, stiffening features, tolerance expectations, and why every feature should be reachable in one tool direction.
