Study of powder densification under hydrostatic loads at high temperatures using finite element method
(Elsevier, 2020)
Many different constitutive models that describe the behaviour of metal powder during hot isostatic processes are found in literature. A quantitative comparison of these material laws shows a huge discrepancy among the ...
Optimization of the semi-hexagonal geometry of a composite crush structure by finite element analysis
(Elsevier, 2016)
In the present paper a numerical model for predicting the crushing behaviour of semi-hexagonal E-glass/polyester composite structures has been developed. Qualitative and quantitative analysis have shown that the results ...
A multiscale material model for metallic powder compaction during hot isostatic pressing
(Elsevier, 2023)
The prediction of the distortions during Near-Net-Shape Hot Isostatic Pressing (NNS-HIP) is an intrinsic multiscale problem where the local interactions among particles determine the macroscopic distortions taking place ...
Zientziak bizidunontzat: Tokiko curriculumak Euskal Herri osasuntsurako hezkuntzan
(Universidad del País Vasco = Euskal Herriko Unibertsitatea, 2023)
Egun bizi dugun krisi ekologiko globalaren garaian, berebiziko garrantzia dute biodiber-tsitatearen eta gure ingurune naturalaren zaintzak. Izan ere, orain gutxi izandako pandemiak inoiz baino ar-giago erakutsi ...
Gamifying Software Engineering Subject to Enhance the Quality of Knowledge
(Wiley, 2024)
Gamification has been widely used in education in recent years. Gamification has been proven to be a useful tool for students, as it motivates them and helps them to learn. The lack of motivation on the part of the students ...
Thermodiffusion, diffusion and Soret coefficients of binary polymeric mixtures in toluene and cyclohexane
(De Gruyter, 2024)
We present the results of experimental study on measuring the thermodiffusion, molecular diffusion and Soret coefficients of polystyrene (4,880 g/mol) in the pure solvents toluene and cyclohexane at 298 K and atmospheric ...
GenMorph: Automatically Generating Metamorphic Relations via Genetic Programming
(IEEE, 2024)
Metamorphic testing is a popular approach that aims to alleviate the oracle problem in software testing. At the core of this approach are Metamorphic Relations (MRs), specifying properties that hold among multiple test ...
Mechanical Properties and Fatigue Performance of 17-4 PH Stainless Steel Manufactured by Atomic Diffusion Additive Manufacturing Technology
(MDPI, 2023)
Additive Manufacturing (AM) is gaining importance as an alternative and complementary technology to conventional manufacturing processes. Among AM technologies, the Atomic Diffusion Additive Manufacturing (ADAM) technology ...
Bending rigidity, sound propagation and ripples in flat graphene
(Springer Nature, 2024)
Many of the applications of graphene rely on its uneven stiffness and high thermal conductivity, but the mechanical properties of graphene—and, in general, of all two-dimensional materials—are still not fully understood. ...
Effect of the loading-rate and stress state on the constitutive modelling and fracture of 2205 Duplex stainless steel
(Elsevier, 2024)
Shear cutting is a high-speed forming process where material separation is involved. The nature of the process leads to high strain rates and temperatures on the sheared zone of the material subjected to the operation. In ...
