Variation of Mechanical Properties of Structural Components of Hoisting-and-Conveying and Construction Machinery under Dynamic Stresses

Dynamic force (vibration and impulse force) modifies mechanical properties and flow behavior of solid bodies. Experiments in shearing of reinforcement bars with vibration (7.9 kHz) conducted by authors and S.A. Evtjukov at the Department of Construction Machinery of SPbGASU (Saint Petersburg State University of Architecture and Civil Engineering) revealed the reduction of the static part of the...

Bottle Conveying Simulation

The Virtual Race Track, VRT, suite of simulations is the most recent addition to the automation tools known as Virtual Package Simulation, VPS, for analyzing the performance of plastic bottles. These new simulations predict the dynamic performance of bottles traveling on conveyors. The objective is to determine if the bottles remain standing after impacting fixed guide rails and gates. The bott...

Elevating Mallarmé’s Shipwreck

This paper discusses collage as a means to explore spatial ideas. It concerns the practice of drawing-as-research, the spatiality of drawing and the nature of paper. It questions the homogeneity of digital tools in contemporary practice. It is introduced with a discussion of architectural representation and space with a historical trajectory. It questions an understanding of space-as-geometry a...
