Abstract(J)	超ハイテン材プレス部品の残留応力発生プロセスを把握するため，ソリッド要素を用いたせん断-成形加工連成FE解析を実施した．せん断加工解析後，及びそれを引継いだ成形加工解析後の端面残留応力は，実測結果の傾向と概ね整合したことから，各加工因子の残留応力に及ぼす影響を評価するための有効なツールとなり得る． Translation
Abstract(E)	To understand the residual stress generation process in press-formed parts made of ultra-high strength steel, coupled FE analysis of shearing and forming using solid elements was conducted. The predicted residual stress at the edge after shearing and subsequent forming was generally consistent with the trends observed in actual measurements, indicating that this approach can be an effective tool for evaluating the influence of various factors during processing.

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.

Search tips

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