Designs, Vol. 8, Pages 37: Investigation on the Microstructure and Micro-Mechanical Properties of Thermal-Sprayed NiCoCrAlY High Entropy Alloy Coating Designs doi: 10.3390/designs8020037 Authors: Animesh Kumar Basak Nachimuthu Radhika Chander Prakash Alokesh Pramanik NiCoCrAlY high entropy alloy (HEA) coating (47.1 wt.% Ni, 23 wt.% Co, 17 wt.% Cr, 12.5 wt.% Al, and 0.4 wt.% Y) was deposited on a stainless steel subtract by atmospheric plasma spraying (APS). The as-deposited coating was about 300 μm thickness with <1% porosity. The microstructure of the coating consisted o ..read more

Designs, Vol. 8, Pages 33: Designs of Optomechanical Acceleration Sensors with the Natural Frequency from 5 Hz to 50 kHz Designs doi: 10.3390/designs8020033 Authors: Marina Rezinkina Claus Braxmaier In many applications, such as space navigation, metrology, testing, and geodesy, it is necessary to measure accelerations with frequencies ranging from fractions of a hertz to several kilohertz. For this purpose, optomechanical sensors are used. The natural frequency of such sensors should be approximately ten times greater than the frequency of the measured acceleration. In the case of triaxial ac ..read more

Designs, Vol. 8, Pages 32: From Generation to Reuse: A Circular Economy Strategy Applied to Wind Turbine Production Designs doi: 10.3390/designs8020032 Authors: Ana Rita Caramelo Paulo Santos Tânia Miranda Lima The environmental impact of wind turbine rotor blades, both during manufacturing and at the end of their life cycle, can be significant. The aim of this study was to define and test a methodology for recycling the waste resulting from their production. Particles of waste from the mechanical machining of rotor blades, which were made up of a glass fibre/epoxy matrix mixture, were used to ..read more

Designs, Vol. 8, Pages 31: Finite Element Analysis of Patient-Specific Cranial Implants under Different Design Parameters for Material Selection Designs doi: 10.3390/designs8020031 Authors: Manuel Mejía Rodríguez Octavio Andrés González-Estrada Diego Fernando Villegas-Bermúdez This work presents the study of the thickness vs. stiffness relationship for different materials (PMMA and PEEK) in patient-specific cranial implants, as a criterion for the selection of biomaterials from a mechanical perspective. The geometry of the implant is constructed from the reconstruction of the cranial lesion us ..read more

Designs, Vol. 8, Pages 30: The Design of Earthquake Evacuation Spaces Based on Local Wisdom: A Case Study of Traditional Houses in South Sulawesi Designs doi: 10.3390/designs8020030 Authors: Dany Perwita Sari Mutmainnah Sudirman Andi Asmuliany Indonesia is situated on the Ring of Fire, which causes a lot of earthquakes. On the 28 September 2018, there was an earthquake in Palu, Sulawesi Island, Indonesia, which was one of the strongest shakings since 1980. Surprisingly, most traditional houses in Sulawesi survived. There has been some research on adapting traditional house structures to modern ..read more

Designs, Vol. 8, Pages 29: Aircraft Structural Design and Life-Cycle Assessment through Digital Twins Designs doi: 10.3390/designs8020029 Authors: Sérgio M. O. Tavares João A. Ribeiro Bruno A. Ribeiro Paulo M. S. T. de Castro Numerical modeling tools are essential in aircraft structural design, yet they face challenges in accurately reflecting real-world behavior due to factors like material properties scatter and manufacturing-induced deviations. This article addresses the potential impact of digital twins on overcoming these limitations and enhancing model reliability through advanced updati ..read more

Designs, Vol. 8, Pages 28: The Biomechanical Analysis of Tibial Implants Using Meshless Methods: Stress and Bone Tissue Remodeling Analysis Designs doi: 10.3390/designs8020028 Authors: Ana Pais Catarina Moreira Jorge Belinha Total knee arthroplasty (TKA) stands out as one of the most widely employed surgical procedures, establishing itself as the preferred method for addressing advanced osteoarthritis of the knee. However, current knee prostheses require refined design solutions. This research work focuses on a computational analysis of both the mechanical behavior of a knee joint implant and ..read more
