All my paintings have deep, personal meaning. Much of my art is interwoven with intricate patterns and the delicate application of gold leaf to further conceptualize my themes. My paintings are explorations of my dreams, emotions and imagination. My inspiration is my personal experience with love, loss, and infinite joy. During my past three decades as an artist I have been an ardent supporter of a number of youth art programs in the Bay Area and spent time an instructor at the Lilian Paley Center for the Visual Arts in Oakland, California. Recently, one of my paintings was chosen for the cover of the college textbook, “Gendered Lives”, by Julia T. I have had numerous solo exhibitions over the years including an exclusive event in which I partnered with Mercedes-Benz of California. I'm based in the San Francisco Bay Area where my work is shown in galleries, corporate spaces, restaurants, and cafes. With the increase of the nugget diameter, the durability and service life of a body decreases.Thank you for checking out my portfolio.
The team also found out that the service life of a vehicle body can be affected by the nugget diameter of spot welding joints (connection points at which two sheets are welded together). Moreover, the front of a vehicle body turned out to be twice more prone to damage than the rear, regardless of the speed and road type.
For example, 100 spot weld joints were damaged when the model moved on a type E road at the speed of 5 km/h 50-at 15 km/h, and only 40-at 10 km/h. The results of this studyshow that low speeds on bumpy roads can cause more body damage than medium ones. So, 72 values had to be calculated for each experiment," said Kazem Reza Kasyzadeh, an associate professor at the Department of Mechanical and Instrumental Engineering of the Engineering Academy, RUDN University. Bumpy road follow along A poster to loosen my designers block. Each of these 12 points is affected by six force and momentum components. "We modeled the movement of a vehicle on different types of roads and at different speeds and measured force and momentum at 12 suspension attachment points, that is, the points at which the suspension transmits the load to the body. With 4 types of roads and 3 speeds on each of them, the team conducted 12 experiments in total. Type E was assigned to the bumpiest of all roads on which the speed was only 5, 10, and 15 km/h. For example, type B was an almost perfectly smooth road with no bumps and the model moved on it at the speed of 50, 70, and 90 km/h.

Then, the research team created a computer simulation in which the 'car' moved on different types of roads at different speeds. Download and use 70,000+ Road stock photos for free. It describes interactions within a system of details that move relative to one another. 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.
