Abstract(E)Systematic 3-point bending crash tests were conducted with high strength steels using an M-shaped structure in order to influence the effect of material properties on crash performance. Materials with a wide range of tensile strengths from 590 MPa to 1800 MPa and various thickness from 1.2mm to 1.6mm are examined. The experimental results clarified the effects of sheet thickness, material strength on crash characteristics. Based on the experimental results, a simple method for estimation of bending crash performance using material strength and thickness as parameters was proposed in order to understand the relationship between the weight reduction effect and improvement of crashworthiness in automotive parts when using advanced high strength steels. Numerical simulation considering fracture behavior are carried out to estimate the crash performance and risk of fracture for the ultra-high strength steels. The results of the simulations shows good coloration with the experimental results.

About search


How to use the search box

You can enter up to 5 search conditions. The number of search boxes can be increased or decreased with the "+" and "-" buttons on the right.
If you enter multiple words separated by spaces in one search box, the data that "contains all" of the entered words will be searched (AND search).
Example) X (space) Y → "X and Y (including)"

How to use "AND" and "OR" pull-down

If "AND" is specified, the "contains both" data of the phrase entered in the previous and next search boxes will be searched. If you specify "OR", the data that "contains" any of the words entered in the search boxes before and after is searched.
Example) X AND Y → "X and Y (including)"  X OR Z → "X or Z (including)"
If AND and OR searches are mixed, OR search has priority.
Example) X AND Y OR Z → X AND (Y OR Z)
If AND search and multiple OR search are mixed, OR search has priority.
Example) W AND X OR Y OR Z → W AND (X OR Y OR Z)

How to use the search filters

Use the "search filters" when you want to narrow down the search results, such as when there are too many search results. If you check each item, the search results will be narrowed down to only the data that includes that item.
The number in "()" after each item is the number of data that includes that item.
