Keywords • ABS (acrylonitrile butadiene styrene) • vibration • deposition direction • frequency response function • additive manufacturing Abstract This article compares the vibrational behaviour variability of acrylonitrile butadiene styrene (ABS) test specimens obtained by additive manufacturing (AM) with three different deposition directions. Te...
Metal sheet anisotropy is the directional dependence of mechanical properties. It is the key factor that must be considered when using numerical simulation to predict any manufacturing process that involves plastic deformation. The plastic strain ratio, also known as Lankford coefficients or R values, together with the forming limit curves (FLC), a...
Sheet metal anisotropy is the directional dependence of mechanical properties. It is a critical factor that must be considered when using numerical simulation to predict any plastic deformation manufacturing process. Sheet metals prove anisotropic plastic behaves due to crystallographic texture caused by progressive rolling steps, Banabic D. et al....
This paper investigates the effects of layers orientation on impact energy absorbed by acrylonitrile butadiene styrene (ABS) test specimens, obtained by additive manufacturing (AM), having three in‐plane deposition directions (0°, 45°, and 90°). The specimens were tested with instrumented Charpy hammer, CEAST 9050 Pendulum Impact System, according...
Polycarbonate composites are widely spread in many industries, for product manufacturing. Although these materials are being used with high fidelity, their mechanical properties will highly depend on: manufacturing processes, fiber orientations with respect to external loads, type of loading, environmental conditions etc.
This paper presents the Ch...
Magnesium alloys are widely used in automotive (steering wheel frames) and aerospace due to their lightweight, ductility, energy absorption and castability properties. Finite Element Analysis and design optimisation have driven the improvement of structural crashworthiness, stiffness, strength, durability, and NVH (noise vibration, harshness) perfo...
Purpose
The purpose of this paper is to focus on the structural integrity of the rainwater propeller pumps installed in the municipal wastewater treatment plant (WTP).
Design/methodology/approach
A numerical analysis is performed to determine the maximum shear stress on the fasten bolts. The rainwater propeller pump is examined in operation at n...
