通过考虑半无限弹性体和具有带缺陷的轻微波浪形表面的刚性体之间的粘附，提出了涉及改变弹性体的弹性模量的可逆粘合剂接合。粘附表面的分离应力理论上表示为弹性模量的函数。然而，分离应力的表达式根据粘附区域的最大半接触宽度的条件和取决于弹性模量、粘附功和表面粗糙度的参数而变化。根据最大半接触宽度和上述参数，将分离机理分为六种类型，并进行了理论分析。通过利用弹性模量可变的弹性体，可以控制分离应力，并且可以重复地将弹性体粘附到物体和从物体分离。
Reversible adhesive joining that involves altering the elastic modulus of an elastic body is proposed by considering adhesion between a semi-infinite elastic body and a rigid body that has a slightly wavy surface with defects. Separation stress of adhered surfaces is theoretically expressed as a function of the elastic modulus. However, the expression of the separation stress varies depending on the condition of the maximum half contact width of the adhesion area and a parameter that depends on the elastic modulus, the work of adhesion, and the surface roughness. Therefore, separation mechanisms are categorized into six types by considering the maximum half contact width and the above parameter, and theoretically discussed. By utilizing an elastic body which has variable elastic modulus, the separation stress can be controlled and the elastic body can be repeatedly adhered to and separated from an object.
