“…Subsequently, a second region with lower stiffness than the initial one characterizes a plastic behavior. Finally, an increase in stiffness until the strain of the specimen (Figure 8 (d)) implies a behavior characteristic of a plastic material [17].…”

The polymers used as interlayers in the laminated glass support the tensile stresses, keeping the glass fragments fixed in the film and avoiding possible accidents. This article aims to characterize the polymers Polyvinyl Butyral and Sentryglas®, as their physical-chemical and mechanical properties. It may help a laminated glass company located in Bahia to optimize its production process. We tested the samples to Fourier Transform Infrared Spectroscopy (FTIR), Thermogravimetric Analysis (TGA), and Tensile. The results allowed us to characterize the materials technically, comparing them with the data from the sheets provided by their manufacturer. In addition, it has provided the Laminated Glass Factory with data that can reduce costs and improve production.

“…The stress-strain curves of PVB films have a small nonlinear elastic area, and a region in which their stiffness gradually increases until rupture [17,18]. Therefore, PVB is considered a hyperelastic material, in which the stretching of the mesh becomes increasingly tricky as the chains are tractioned, resulting in its stiffening [19].…”

Glass material is largely used in buildings and facilities due to various motivations. Besides, glass still represents a vulnerable component for building occupants. Careful attention is required especially for glass elements that may be subjected to extreme design loads, such as impact, vibrations, etc. Among various approaches and techniques to prevent danger for people in case of glass breakage, multilayer antishatter safety films (ASFs) are commercially available for the retrofit of existing monolithic glass members. In the present research study, a multistep experimental program is presented to obtain the characterization of key input mechanical parameters that are required for the numerical analysis of glass elements protected by ASFs. Relevant characteristics are derived for the definition of an equivalent material and monolithic tape able to reproduce the ASF experimental outcomes. On the side of experiments, artificially aged specimens (healing process) are investigated. A major advantage is taken from small-scale peel and tensile tests on ASF samples, as well as Operational Modal Analysis (OMA) techniques for nondestructive vibration measurements on preliminary fractured specimens of ASF-bonded glass elements. Efficient Finite Element (FE) numerical models calibrated with the support of experimental data and Cohesive Zone Modelling (CZM) techniques are presented for discussion of comparative results, giving evidence of rather good estimates and possible extension of the multistep experimental procedure.

Tensile tests make it possible to determine the resistance and other relevant parameters of the materials. These procedures are usually performed with equipment that is expensive and inaccessible to higher education centers with limited budgets. In the case of acquiring this hardware, the disadvantage is that this are purely manual machines that make the use and learning process difficult. That is why this document shows the construction of a machine that allows this type of testing, but using low-cost materials. The mechanical and electronic design and programming that has been used to implement and semi-automate the machine is briefly but clearly described. To validate the functionality, the respective tests have been carried out, although it is a limited version that requires improvements, the results are satisfactory. The curve obtained when carrying out tests with A36 steel has shown a similarity with the theory. Thus, students obtain a technological tool that contributes to academic training, strengthening knowledge in the study of materials.
