CONCEPT OF CRASH SAFETY AND TECHNICAL APPROACH OF STUDY.

1. Crash Safety :
Material technologies are also expected to contribute
to improving crash-worthiness. In order to achieve a
safe car body in the event of a collision,deformation
of the cabin structure should be minimized to protect
the occu-pants, and the collision energy should be
absorbed in a short deformationlength within the
crushable zones

2. Conceptofcrash safety

3. Relationship between static strength and dynamic
strength

4. Part weight reductions achieved by using high-strength steel
with a higher k-value
the average reactive force of a rectangular tube with a hat-
shaped cross section is related to the k-value, i.e., the
dynamic/static ratio of yield strength
