Impact of bolt positioning on the stiffness of angular support brackets
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2024)Bolts and screws are usually preferred over other joining techniques when assembly and disassembly operations are required. However, they add extra weight to the system, so it is essential to reduce their size and weight ... -
Design strategy for the prototyping of 3D-printed continuous fiber-reinforced components for solar-powered vehicle
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2024)Continuous fiber fused filament fabrication is an advanced 3D printing method that allows designers to produce high-performing lightweight structures, leading toward innovative design philosophies and sustainable production ... -
Tomographic and mechanical study of 3D printed porous polymer structure under compression
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2024)This study investigates the influence of open porosity rate and trabeculae diameter on the compressive behavior of structure printed by DLP technology. Three types of structures have been studied : two periodic structures ... -
Characterization of woven composite material under multiaxial loading regimes using FE-based stereocorrelation
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2024)In this paper, woven glass fiber composite samples were subjected to three different cyclic loading histories (i.e., tensile, shear and combined loading at 45° via the Modified Arcan Fixture. During the experiments, the ... -
Fatigue analysis on flax-epoxy composites: insights and implications
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2024)This study investigates the performance of flax fiber and epoxy resin composites, focusing on fatigue testing, which is scarcely reported in the literature. Fatigue behavior is evaluated under full reverse bending loading ... -
Design of the testing procedure for investigation of Eryx conicus dermal armour characteristics
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2024)The aim of this work is to develop an experimental method suitable for the mechanical testing of highly non-standard biological samples such as snake skin with osteoderms. The objective of the method is to determine, whether ... -
Tribo-technological features of laser powder bed fusion process: scratch and wear resistance of AlSi10Mg aluminium alloy
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2024)Mechanical systems, regardless of their complexity, very often require that different parts must move relative to each other by sliding their surfaces, therefore appropriate tribological properties are needed. This request ... -
Assessment of local mechanical properties of laser powder bed fused aluminium alloy by non-destructive testing based on FIMEC indentation
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2024)Laser powder bed fusion process is a versatile metal additive manufacturing process. Although significant progress has been made so far, there is still limited large-scale adoption of this technique by the industry. The ... -
Ageing effects on the mechanical properties stability of 3D printed material under compression
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2024)The paper deals with the examination of the ageing effects on the mechanical properties stability of 3D printed material via stereolithography under compression when subjected to various conditions, including UV radiation, ... -
A geometry projection method for designing and optimizing additively manufactured variable-stiffness composite laminates
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2024)A method for designing laminates is presented using geometry projection to optimize the layout of additively manufactured variable-stiffness composite laminates. By considering fiberreinforced bars as geometric primitives, ... -
Comparison of elastic properties of periodic and aperiodic porous structures produced by additive methods
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2024)The aim of this work was to design, print, and examine elastic properties of porous structures with various parameters and beam distributions. These structures, generated using an algorithm, featured three types of lattices: ...
