通過粘合劑粘合在一起的兩層材料被迫彼此滑動（wu剝離），從而在粘合劑層中引起剪切，并終使其破裂。粘合剪切模量可以通過多種測試方法進(jìn)行表征。兩種常見的方法是搭接（測試平面剪切以找到剪切模量和剪切強(qiáng)度）和對接（測試?yán)烨哉业郊羟心Ａ亢蛷椝苄詤?shù)）。平面剪切測試意味著移動的壓板在與粘結(jié)相同的平面中移動。在這些配置下，樣品被假定為一個的矩形，其頂部和底部表面地附著在兩個平坦的基板上（防滑邊界條件），盡管此配置也可以記錄粘滑的力與位移數(shù)據(jù) 物理粘附。

典型應(yīng)用：

1、夾芯夾層材料剪切性能測試（ASTM C273/C273M - Standard Test Method for Shear Properties of Sandwich Core Materials）

2、ASTM D5656-拉伸載荷剪切作用下厚粘劑金屬搭剪連接的應(yīng)力應(yīng)變行為測試

4、通過拉伸載荷測定搭接剪切狀態(tài)下組織粘合劑強(qiáng)度特性

塔接夾具-低力（帶有凝膠制備室）

測試膠粘劑的質(zhì)量時，測試膠粘劑沿粘合界面的抗剪切力的重要性能。在這種情況下，重要的是小化層之間的剝離，這可能會大大降低粘結(jié)的耐搭接剪切強(qiáng)度。基于專為在硬質(zhì)塑料和金屬部件中實現(xiàn)牢固粘合而設(shè)計的夾具，這些夾具已針對測試生物材料或組織之間的粘合特性進(jìn)行了化。它帶有一個te殊的固定器，該固定器旨在促進(jìn)直接注入兩個壓板之間的水凝膠的原位制備，以大程度地減少暴露于空氣中。在水凝膠的情況下，還可以測量凝膠的剪切強(qiáng)度及其與壓板材料的粘附性。
