Abstract(J)接着接合は異種材料の接合に適しており、その疲労強度の把握は重要な課題である。前報の接着層応力解析および試験片の疲労試験結果より、アルミ合金板を被着体とした接着接合部の疲労特性を調査する。また、被着体剛性および特性の異なる接着剤の疲労試験結果を比較し、数値解析により得られた指標による整理を試みた。

Translation

Abstract(E)This paper describes an investigation results for the fatigue strength of adhesive bonding joints. Recently, non-ferrous metals are adopted to the light weight automotive bodies. The adhesive bonding has advantages about joining different materials. It is important to clarify the fatigue properties for the adhesive bonding in car body. In previous reports, stress distributions on adhesive layers are analyzed, and fatigue tests are carried out in different adherences and adhesive properties. In this paper, fatigue tests are evaluated by numerical results, and proposed methodology is considered to be efficient for fatigue strength design for structural adhesives.

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.
