Maybe the author of this article can answer these questions about content in the article or text that I removed from the article.
Thanks, Mr. Finkelstein, for your valued comments. I will quickly answer your questions by now within the talk page, and later work more on the article:
- What is the ESI company, and what is the program HEMP-ESI?
ANS: ESI is a group of engineering consulting companies of which I was a scientific director up to my retirement (http://www.esi.fr/). HEMP-ESI is a computer program that was used in the 70s - 80s by ESI for early crash simulations (and other).
- I removed this sentence from the page because it doesn't make any sense to me. Maybe someone can clarify it and reinsert it: Major results are the preservation of the cabin survival space and acceleration loads on vehicle occupants.
ANS: What was meant was that the space in the cabin of the car (where the occupants are sitting) should not be crushed during a crash, but remain intact, with car doors remaining openable. And: The decelerations upon a car crash impact shall be survivable. I'll try to clarify this later. ANS2: I added to the second paragraph: "Important results are the deformations (e.g., steering wheel intrusions) of the occupant space (driver, passengers) and the decelerations (e.g., head acceleration) felt by them, which must fall be below threshold values fixed in legal car safety regulations. To model real crash tests, todays crash simulations include virtual models of crash test dummies and of passive safety devices (seat belts, airbags, shock absorbing dash boards, etc.).
- The author's references include "Haug, 1981", and I think that is the author himself, but it would be good to see a correct reference at the bottom of the page, or in the text at least, according to Wikipedia:Cite sources.
ANS: I'll redo the referencing. ANS2: I added the references: Haug, E. (1981) "Engineering safety analysis via destructive numerical experiments", EUROMECH 121, Polish Academy of Sciences, Engineering Transactions 29(1), 39–49. Haug, E., Scharnhorst, T., Du Bois, P. (1986) "FEM-Crash, Berechnung eines Fahrzeugfrontalaufpralls", VDI Berichte 613, 479–505.
