plastic strain of steel
(OP)
For standard steel grade (S275)can someone explain (in simple terms if possible) how a local plastic strain value of 0.02 (max) may be used when examining stresses in thin plates ( < 10mm)due to explosion type loading. Plastic deformation of the plate is permitted.





RE: plastic strain of steel
in standard tensile testing the yield stress is conventionally determined at the strain of 0.02%.
For work hardened explosion loaded sheets, the yield stress will be found much higher, if a specimen of the deformed sheet can be machined into a tensile test specimen and tested.

RE: plastic strain of steel
Can you re-state your question? I did not really understand what information you need.
Goahead and Metalguy,
Just as a clarification, harryj wrote 0.02 plastic strain, which is 2% strain/elongation.
