Sustainable reinforced concrete design of structural walls
(Peer reviewed; Journal article, 2021)Sustainability calls for reduction in the use of natural resources and man-made materials. In light of this, the present study demonstrates the potentials of the reduction of transverse reinforcement in structural walls. ... -
Environmental impact of material selection in a car body component – The side door intrusion beam
(Peer reviewed; Journal article, 2021)As the impact of transport on the issue of global warming is considerable, the fleet-wide average emission target for new cars is continuously lowered. Car weight reduction is considered as one of the possible strategies ... -
The Influence of Wedge Angle, Feedstock Color, and Infill Density on the Color Difference of FDM Objects
(Peer reviewed; Journal article, 2021)The surface appearance in additive manufacturing (AM) has attracted attention in recent years due to its importance in evaluating the quality of 3D printed structures. Fused Deposition Modeling (FDM), also known as Fused ... -
On the low reinforcing efficiency of carbon nanotubes in high-performance polymer fibres
(Peer reviewed; Journal article, 2021)Driven by the exceptionally high mechanical properties of carbon nanotubes (CNTs), over the years an extensive research effort has been devoted to the reinforcement of high-performance polymer fibres with CNTs. However, ... -
Fatigue Crack Growth Rate at Material and Geometry Transitions in Glass-Epoxy Composites
(Peer reviewed; Journal article, 2021)An element test specimen with ply drops, intended to be representative of a composite structure of varying thickness such as the main laminate in a wind turbine rotor blade structure, is used to investigate the fatigue ... -
Experimental investigation of the path-independent fracture of composites
(Peer reviewed; Journal article, 2021)Cohesive zone modelling is the main tool to solve the problems of crack initiation and growth, and therefore several mixed-mode cohesive laws are being developed. The majority of the cohesive laws are path independent ... -
