… An adhesive is a substance that is placed between objects for the purpose of adhesion. First, adhesives have the property of adhering to the adherend, and second, they cohere and resist deformation and destruction. Therefore, failure of an adhesive formed using an adhesive can occur at the interface between the adhesive and the adherend (or adhesive failure), or within the adhesive layer, called cohesive failure. Also, when the adhesion is so strong that the adherend itself breaks, this is called cohesive failure of the adherend (adherend failure), but it is sometimes called material failure. … *Some of the terminology used to refer to "cohesive failure" is listed below.

… 接着の目的で物体間に介在させて用いる物質は接着剤adhesiveであるが,接着剤は第1に,被着体adherendに対して接着する性質をもち,第2に,自身は凝集cohesionして変形および破壊に対して抵抗する。したがって,接着剤を用いて形成した接着の破壊には,接着剤と被着体の界面破壊interfacial failure(あるいは接着破壊)と,接着剤層内で破壊が起こる凝集破壊cohesive failureがある。また,接着が強くて被着体自身が破壊する場合は被着体の凝集破壊(被着体破壊)であるが,材料破壊と呼ばれることがある。… ※「凝集破壊」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
