This study investigated the 3D-printed PLA (Polylactic Acid) workability during operation of milling. It is difficult to obtain as a result Fused Deposition Modeling (FDM) 3D printing very strict tolerance, and good roughness surface. A possible solution can be usage last milling that complete workpiece in terms desired dimension tolerances. design experiments (DOE) analysis has been applied observe optimizing result. Three factors have analyzed: feed rate, depth cut, rotational speed. Two...
The fight against climate change has delineated new objectives, among which one of the most crucial is replacement high-energy-intensity materials in construction sector with more sustainable and thermally efficient alternatives to reduce indirect emissions. Consequently, thermal properties assume fundamental importance. In this regard, large-scale use earth represents a promising option, not only due its widespread availability but especially for minimal embodied energy. However, enhance...
Abstract In the past few decades, need for efficient and reliable Structural Health Monitoring strategies has led to development of several approaches damage detection characterization purposes. Among them, Nonlinear Vibro-Acoustic Modulation (VAM) exploits modulation arising from interaction two concurrently applied driving waves, namely probe pump excitations, in presence nonlinear scatters such as cracks defects. Therefore, VAM provides information on emergence internal by extracting...
FSP is a relatively new technique that changes the microstructure on surface of material to improve mechanical properties in desired zone. This study aimed investigate quality AA2098 sheets after being subjected friction stir processing under different conditions feed rate and rotational speed. A DoE analysis was developed with two factors, speed, three levels 75, 100, 125 mm/min 1000, 1250, 1500 rpm respectively, order assess processed quality. The Sa parameter used represent zones process,...
Abstract The dissipative properties of road pavements may have beneficial effects to reduce vehicle vibrations, traffic noise, vehicles-structure dynamic interaction, and degradation pavement materials. Assessing the capacity damping is, therefore, critical importance. Such assessment has been mainly conducted in recent years by laboratory-scale experiments, while little effort devoted in-situ tests. latter are, fact, cumbersome for practical reasons typically require a more advanced data...
