Manufacturing method for a metallic part and associated metallic part

20:

• The manufacturing process as recited in claim 19 wherein the first and second directions form with one another an angle α from 30° to 90°.

21:

• The manufacturing process as recited in claim 19 wherein the first and second directions form with one another an angle α from 60° to 90°.

22:

• The manufacturing process as recited in claim 19 wherein the first and second directions form with one another an angle α from 80° to 90°.

23:

• The manufacturing process as recited in claim 19 wherein the first and second sub-blanks are assembled together in the pre-assembly area by spot welding.

24:

• The manufacturing process as recited in claim 19 wherein the first and second sub-blanks are assembled together in said pre-assembly area by adhesive bonding.

25:

• The manufacturing process as recited in claim 19 wherein the stamping operation is performed by hot stamping.

26:

• The manufacturing process as recited in claim 19 wherein the stamping operation is performed by cold stamping.

27:

• The manufacturing process as recited in claim 19 wherein the sliding area of the overlap area further comprises at least one post-assembly area where the first and second sub-parts are still overlapping one another after the stamping operation is performed and further comprising a post-assembly step after the stamping operation where at least the first and second sub-parts are joined together in the at least one post-assembly area.

28:

• The manufacturing process as recited in claim 27 wherein the post-assembly step is performed by spot welding.

29:

• The manufacturing process as recited in claim 27 wherein the post-assembly step is performed by laser welding.

30:

• The manufacturing process as recited in claim 19 wherein the stamping operation is followed by a conforming operation using a conforming punch comprising a conforming gap in between the areas corresponding to the first and second sub-parts, the conforming gap being smaller than the gap of the initial stamping tool.

31:

• The manufacturing process as recited in claim 19 wherein the metallic part comprises a further first sub-part extending along said first direction and being connected to the second sub-part, wherein the flexible metallic blank comprises a further sub-blank corresponding to the further first sub-part, said flexible blank further comprising a further overlap area where a further first sub-blank overlaps the second sub-blank.

32:

• The manufacturing process as recited in claim 19 wherein the pre-assembly area has a resistance to shear strength RS, expressed in MPa, defined as being the stress necessary to initiate a sliding movement between the first and second sub-blanks, when applying the stress on one side on one of the first and second sub-blanks and on the other side in a direction of the force generated during the stamping operation, the shear strength RS being lower than a maximum force generated in the direction during the stamping operation.

33:

• A metallic part manufactured according to the manufacturing process as recited in claim 19.

34:

• The metallic part as recited in claim 33 wherein the first and second subparts are contiguous and have at least one set of two contiguous vertical walls, a curvature radius measured in a transition area between the two contiguous vertical walls being equal to or less than twenty times a smallest thickness of the first and second two sub parts.

35:

• The metallic part as recited in claim 33 wherein the metallic part is an automotive vehicle body part.

36:

• An automotive vehicle comprising the metallic part as recited in claim 35.
