Moreover, the core components of the sandwich structures used the material properties of polyvinyl chloride (PVC) 70.75. The mechanical properties of PVC 70.75 for this T-joint model were acquired from the work done by Caliskan et al. [14], as listed in Table 2. These properties of PVC 70.75 were obtained from the stress-strain curve as the result of compression testing to the specimen of the relevant material.

Afterward, the cohesive layer on this T-joint model was modelled with Araldite 2015 material. The mechanical properties of Araldite were attained from the article by Caliskan et al . [14]. The Araldite material properties for adhesive thickness of 0.25 mm are given in Table 3. Meanwhile, the support block, clamps and impactor were modelled as rigid body, since those components are not components of interest to be analysed.
