To develop this model, scientists used the so-called multibody dynamic method. Using this model, one can assess fatigue resistance of a car without conducting expensive experiments. An associate professor from RUDN University created a mathematical model that describes all possible damages of spot welded joints caused by fatigue failure. The level of fatigue resistance can be measured experimentally, but it requires a lot of expendable supplies and a testing site with special equipment. A vehicle body with damaged spot welded joints has lower level of vehicle crashworthiness. The vehicle body structure is the main load-bearing part among other parts of the car. Cyclic stress leads to the formation of micro-cracks, and after some time, spot welded joints fail. An article about this study was published in the Simulation Modelling Practice and Theory journal.Ī car on a bumpy road is subjected to different dynamic loads that causes fatigue failure. The results of the study can help measure fatigue resistance in vehicles more accurately. According to his computer simulation, low speed on bumpy roads can be more dangerous for a vehicle body than moderate. view moreĪn associate professor from RUDN University developed a computer model that describes all types of vehicle body damage caused by fatigue failure.

"I will be around after the upcoming summer. Hainer, Kahn, and Salihamidzic insisted on concentrating on sporting issues until the decisive board meeting scheduled for May 22. Reports suggest that Kahn may have to fight for his job despite a contract running until 2024. The former German national team goalkeeper denied rumours of resigning but said he is determined to stay in office. Under-fire sporting director Hasan Salihamidzic spoke of a post-World Cup energy problem, while president Herbert Hainer mentioned an in-depth post-season analysis, avoiding backing chairman Oliver Kahn. It's not pleasant, regardless of whether we deserved the criticism, but today we provided the right answer on the pitch," the German international said. We, as a team, had a lot to endure lately. Midfielder Leon Goretzka stated that too much noise within the club remains a problem for the team, aside from a lack of confidence after a flood of critical media reports targeting some of Bayern's players. "Sometimes they seem to need a bit of pressure," he said. Tuchel reported delivering a wake-up call to his squad in the form of an emotional speech ahead of the match against Hertha. Far from delivering an inspired performance, the Bayern coach praised his team for staying fully focused throughout the 90 minutes without losing faith.īayern's one-point advantage over its closest rival Borussia Dortmund seems to leave room for further changes in the first-tier standings. The successor of departed predecessor Julian Nagelsmann spoke about the reaction he had hoped for. He is not surprised by the team's difficulties when it comes to precision, as confidence couldn't grow over the past weeks. At the same time, the 49-year-old praised his team for maintaining control and not losing their grip on the situation. We'll get the job done," striker icon Thomas Muller said, while midfielder Joshua Kimmich expressed his conviction that "we are going to win the National Championship."Ĭoach Thomas Tuchel spoke about the confidence of his squad being at a low point after recent setbacks. With four rounds of matches left until the 2022/23 season's end, statements following the hard-fought 2-0 victory over bottom side Hertha BSC sounded more like self-encouraging whistling in a dark cellar. Burdened by the uncertain future of the club's leaders and the inevitable restructuring of the current squad, the wavering 2020 treble winner might have recaptured the national league lead, but seems far from having gained stability.Įxpectations seem to have dropped as the season's goal now appears to be making the best of a bad situation, such as winning the eleventh national title, following painful exits in the last eight-round of the UEFA Champions League and the German Cup. BERLIN, April 30 (Xinhua) - The path to happiness for Bayern Munich remains a bumpy road.
