Development of a Flexure Mechanism for High-Precision Applications in Scanning Applications
Abstract: The utilization of the Planar XY Flexural Mechanism is extensive in precision motion systems, where it induces relative motion between a fixed support and a motion stage through the utilization of material flexibility. In contrast to rigid link mechanisms, this mechanism presents noteworthy advantages, including zero backlash, frictionless motion, and high-order repeatability, all within a considerably more compact form. Notably, flexure mechanisms are characterized by their construction from a single …

Investigation of Fracture Mechanics in Composite Materials Through Experimental Testing
Abstract: Understanding the fracture mechanics of composite materials is essential to appreciating their durability and structural integrity. The goal of this research article's extensive experimental analysis is to clarify how composite materials fracture under various loading scenarios. The study makes use of cutting-edge experimental methods to describe the beginning, spreading, and eventual failure of cracks in composite structures. An understanding of the fundamental mechanisms controlling fracture in composites is obtained by …

Numerical and Experimental Modal Analysis of Square Sheets of Low Carbon Steel Under Different Boundary Conditions
Abstract: Dynamic analysis of square plates has been a subject of fundamental research interest over several decades. In these analyses, several dynamic aspects such as modal frequencies, occurrence of harmonics, mode shapes, displacement pattern of position vector, location of maximum displacement and damping characteristics are studied which provide critical inputs for structural design engineers. In this paper, a detailed modal analysis (both modal frequencies and mode shapes) of low carbon steel …

Topology optimization of structures with manufacturing constraints in ANSYS Workbench 19.3
Abstract: The topology optimization analysis system of ANSYSWORKBENCH19.3 is widely used in structural design because it includes manufacturing constraints. However, the topology of the structure and the ease of manufacturing will also change depending on how these manufacturing constraints are set and used. This paper studies the methodology to obtain a more convenient topology on manufacturing while minimizing the mass of the structure by rationally setting the manufacturing constraints. An example …

Technological Progress in Thin Wall Austempered Ductile Iron: From Manufacturing to Operation
Abstract: Nowadays, aluminum is used more often than cast iron in the production of cast parts due to the desire to reduce vehicle weight. Theoretically, austempered ductile iron can be used in high strength, light weight parts because thin wall austempered ductile iron (TWADI) components can be produced with strength-to-density ratios that are comparable to those of cast aluminum. Thus, advancements in the technology of thin wall austempered ductile iron are …
