Abstract(J)構造部品に使われる鉄鋼材料は，切断や穴あけ等の加工が施されている．
これらの加工部をもつ構造物の疲労試験では，同部が最弱部になるケースがあり，加工による影響を考慮した設計が必要となる．
本報では，引張強さ1300MPa以上の超ハイテン材に，各種加工が引張疲労強度に与える影響について述べるとともに，穴明き材の穴部を充填した場合の疲労強度回復効果について報告する。

Translation

Abstract(E)Steel sheets used for structural parts are processed such as cutting and drilling.
Those processed portions are often critical for fatigue strength.
So, consideration of processing methods is important in design process.
In this paper, the effects of processing methods and hole filling on fatigue strength are mentioned by results of fatigue test with ultra-high-strength steel (T.S. 1300 MPa grade).

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.

Search tips

When searching by author name, enter the first and last name separated by a space, such as "Taro Jidosha".
