Abstract(J)過去の研究では、突合せ継手における接着強度を特異応力場の強さ(ISSF)一定として簡便に評価できることを示した。本研究ではスカーフ継手の種々の形状・寸法における破壊に至る際に接着界面縁部に発生するISSFの解析を行い、スカーフ継手における簡便な接着強度評価方法について議論を行った。

Abstract(E)The previous study shows the adhesive strength can be expressed as a constant value of the critical ISSF (Intensity of Singular Stress Field) for butt joints. This study deals with the scarf joint considering two ISSFs corresponding to two distinct singular stress fields. How to evaluate the scarf joint strength is described in comparison with the lap joint having similar two ISSFs. The debonding strength for scarf joints and lap joints can be predicted by the singular stress 𝜎𝜎𝜃𝜃𝜃𝜃(10μm).

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.
