Estimation of Wedge Indentation Resistance and Plane Compressive Characteristics of Acrylic PSA

Abstract

This paper aims to estimate the compressive characteristics and indentation resistance of the acrylic Pressure Sensitive Adhesive (PSA) sheet subjected to the plane plate compression and/or the wedge indentation. These two compressive loading tests with the acrylic PSA sheet were carried out experimentally and numerically. Through the experimental tests, it was found that the indentation velocity affected the cutting line force and the compressive velocity as the compressive strain rate affected the compressive pressure. In addition, a Finite Element Method (FEM) analysis of those two loading tests was carried out using a linear viscoelastic model. It was revealed that the elastic modulus estimated by compressive test is appropriate to simulate the wedge indentation.
