Capturing Memory

In my work, I present the moments of true emotional clarity and impactful memories from my life. I strive to provide insight into my experiences and my understanding of others’ motivations. The creative process helps safely guide me through memories of the past and understanding of others. In my abstracted mixed media paintings and crafts, I use bold jewel tones to express strong feelings and passionate emotions. I also incorporate found objects and paints to communicate the layers and varied depth of memories. With the use of these varied materials, I have developed a personal symbolic language that allows me to relay aspects of my life and perceptions. My goal is to explore my past and invite the viewer into my experiences

Vertical Loads Due to Wheat on Obstructions Located on the Floor of a Model Bin

Tests were conducted in a model grain bin to evaluate the vertical loads acting on differently shaped obstructions embedded in wheat during filling, detention, and discharge. The bin had corrugated galvanized steel walls with a 1.83 m diameter and a flat bottom. All tests were conducted in a bin that was centrically loaded and unloaded. Three differently shaped obstructions (disc, cone, and cylinder) were tested; each had a circular base equivalent to 6% of the bin floor area. The obstructions were supported in the bin using a three-legged support structure. Each leg of the support structure rested on a load cell attached to the bin floor. Tests were conducted with the obstructions located in the bin at three different eccentricity ratios (ratio of the centerline of the obstruction to the bin radius, ER = 0, 0.5, and 0.67) and at two different grain heights (height of grain depth to bin diameter ratio, H/D = 0.4 and 0.75). The radial distribution of vertical pressures in the bin varied, with the highest pressure in the center of the bin and the lowest at the bin wall. The largest vertical load on the disc and cone obstructions was measured at the end of filling. The largest load on the cylindrical obstruction was observed immediately after the initiation of bin discharge. At the end of filling and detention, the vertical loads on the disc, cone, and cylinder were 4.8, 3.7, and 4.9 kN, respectively, for obstructions located at ER = 0 and H/D = 0.4. At a location closest to the bin wall (ER = 0.67), the vertical loading on the disc, cone, and cylinder were 4.4, 3.4, and 4.4 kN, respectively. The greatest difference in vertical loading between the location and type of obstruction was on the order of 50%. Bending moments were also observed to act on these obstructions. Bending moments at ER = 0.67 were much larger than those determined at ER = 0.5. For the disc and cone, moments at ER = 0.67 were three times as large as those determined for tests conducted at ER = 0.0. At the onset of discharge, the vertical loading on both the disc and cone decreased significantly, while the vertical loading on the cylinder increased significantly. Recommendations based on Eurocode I were used to predict the vertical loading on the disc and cylinder embedded in grain. This technique did an adequate job of predicting the maximum loading on both obstructions within the bin; however, it did not take into account the effect of unloading on the obstruction forces

Vertical Wall Loads in a Model Grain Bin with Non-Axial Internal Inserts

A study was conducted to estimate the degree of load asymmetry in a bin with non-axial internal inserts. Internal inserts in the form of an annulus segment were attached to the wall, and their influence on vertical wall loads during centric filling and discharge in a model bin were measured. Wall and floor loads were measured in a corrugated-wall model grain bin with a diameter of 2.44 m and a height of 7.3 m filled with soft red winter wheat to a depth of 6.7 m (height-to-diameter ratio of 2.75). Tests were conducted with inserts that extended circumferentially 30°, 60°, or 90° around the bin, having a width of 7.6, 15, or 23 cm and attached to the bin wall at height-to-diameter (H/D) ratios of 0.31, 0.62, or 0.95. These inserts represented between 1% and 8.6% of the bin floor area. The results showed that with centric filling, considerable asymmetry of static wall loads occurred. The asymmetric loading was caused by the horizontal component of the velocity of the grain stream filling the bin, produced by the drag conveyor. This loading created wall moments in the bin of approximately 3 kN-m. The wall moments generated by imperfect centric filling varied depending on the angular position of the inserts. For a 23 cm wide, 90° insert, which was the worst observed situation, the wall moment was approximately 5 kN-m. The onset of symmetric discharge resulted in an increase in vertical wall load and a decrease in the wall moment. A change in flow pattern from mass flow to funnel flow, as well as the influence of the insert, was clearly shown by the change in wall moment with discharge time
