- Concern for the collapse behaviour of ships and offshore structures and their structural components under ultimate conditions. Uncertainties in strength assessment shall be highlighted. Attention shall be given to the influence of response to load combinations including accidents; fabrication imperfections; life-cycle effects; and user approach. Consideration shall be given to the practical application of methods.

- The analysis of data that captures volcanic eruptions and their atmospheric aftermath plays an important role for domain experts to gain a deeper understanding of the volcanic eruption and their consequences for atmosphere, climate and air traffic. Thereby, one major challenge is to extract and combine the essential information, which is spread over various, mostly sparse data sources. This requires a careful integration of each data set with its strength and limitations. The sparse, but more reliable measurement data is mainly used to calibrate the more dense simulation data. This work combines a collection of visualization approaches into an exploitative framework. The goal is to support the domain experts to build a complete picture of the situation. But it is also important to understand the individual data sources, the wealth of their information and the quality of the simulation results. All presented methods are designed for direct interaction with the data from different perspectives rather than the sole generation of some final images.

- The maritime industry is increasingly utilizing high-strength steels for lightweight ship design. While enhanced yield strength is advantageous, these steels retain the same Young's modulus as lower strength steel grades posing challenges in designing slender structures, particularly concerning structural buckling strength. In longitudinal stiffened ship structures, transverse buckling effects, though less significant than longitudinal stresses, can be difficult to predict. Addressing this, the regulatory framework for verifying the buckling of transversely stiffened panels for ships is a topic of substantial international discussion. A research project supported by Fincantieri led the University of Genova to develop a test configuration assessing a slender ship structure's response to transverse loads. The ISSC 2022-2025 Committee III.1 Ultimate Strength is utilizing this test configuration to conduct a numerical benchmark in three phases, with each phase gradually revealing additional experimental data to the study participants. The benchmark aims to predict the entire end-shortening curve as well as ultimate load to understand load redistribution and quantify energy absorption for dynamic events. This paper presents the preliminary results from Phase 1, focusing on diverse modeling strategies impacting outcomes, including element type, mesh size, and interpretation of initial geometric imperfections among participants in the benchmark study.

- Experiential approaches to technology create opportunities for facilitating a wider range of in-car user experiences, however holistic knowledge regarding experiences that car users find enjoyable is lacking. We present the experience themes of the car as a caretaker, the car as a space for relatedness, the car as a space for stimulation, and the car as a space for transition, collected through a holistic study of 16 drivers, using contextual interviews, reflexive photography and the UX curve method. The use of the themes is exemplified through a design example. The experience themes can help designers empathize with users and create design solutions that can support positive in-car experiences, while the methodology used, serves as an example of how user’s experiences with technology can be studied.
