Deep indentation and puncture is a promising alternative as it is an information-rich measurement with the potential to be performed in a high-throughput manner. Despite its promise, the method lacks standardized protocols, and open questions remain about its possible limitations. Addressing these shortcomings is vital to ensure consistent methodology, measurements, and interpretation across samples and labs. To fill this gap, we examine the role of finite sample dimensions (and by extension, volume) on measured forces to determine the sample geometry needed to perform and unambiguously interpret puncture tests. Through measurements of puncture on a well-characterized elastomer using systematically varied sample dimensions, we show that the apparent mechanical response of a material is in fact sensitive to near-wall effects, and that additional properties, such as the sliding friction coefficient, can only be extracted in the larger dimension case where such effects are negligible. © 2024 The Royal Society of Chemistry.}, keywords = {Friction; sampling; High-throughput; Sample volume; Mechanical characterizations; Characterization techniques; Measurements of; Sample geometry; Soft-solid; Softer materials; Finite samples; Near-wall effects}, year = {2024}, eissn = {1744-6848}, pages = {3806-3813}, orcid-numbers = {Berezvai, Szabolcs/0000-0002-6399-583X} } @CONFERENCE{MTMT:34832711, title = {Elliptikus héjak átpattanását meghatározó kritikus paraméterek numerikus és kísérleti vizsgálata}, url = {https://m2.mtmt.hu/api/publication/34832711}, author = {Piri, Barnabás and Berezvai, Szabolcs}, booktitle = {OGÉT 2024 - XXXII.

Calculus is an important undergraduate mathematics course in engineering programmes, which gives the foundation for engineering subjects like mechanics or electronics. Unfortunately, recent experiences show that the performance of students admitting after the pandemic has deteriorated dramatically in recent years. This research aims to analyse the changes in performance and attitudes of first-year students in the aftermath of the pandemic. In our research, we investigated the performance and learning habits of three groups of first-year mechatronics and energy engineering students during Calculus-1 and the related Mechanics subject. The “2018 group” studied maths traditionally, whereas the “2020 group” took online education in the last months of high school and the first year of university. The “2022 group” spent two years of high school at home in remote learning (the significant 10-11th grades, for maths competence), but received in-person education at the university. Learning habit and performance of the students were monitored using EduBase online educational platform. The results of both the qualitative and quantitative analysis have revealed that online education during the pandemic changed the learning habits of the group in 2020 and had only slight effects on their performance in Calculus and Statics. However, for group 2022, where the pandemic affected high-school maths studies, the performance at the university has fallen dramatically resulting in an increased drop-out rate after the first semester. © 2023 SEFI 2023 - 51st Annual Conference of the European Society for Engineering Education: Engineering Education for Sustainability, Proceedings.
