Identifying Elastic Constants for PPS Technical Material When Designing and Printing Parts Using FDM Technology
(MDPI, 2021-02-27)
This paper introduces a methodology to study the anisotropic elastic constants of technical phenylene polysulfide thermoplastic (PPS), printed using fused deposition modeling (FDM) in order to provide designers with a guide ...
Tool Wear Analysis during Ultrasonic Assisted Turning of Nimonic-90 under Dry and Wet Conditions
(MDPI, 2021-08-07)
Nickel-based superalloys are widely used in the aerospace, automotive, marine and medical sectors, owing to their high mechanical strength and corrosion resistance. However, they exhibit poor machinability due to low thermal ...
Reduction of Die Wear and Structural Defects of Railway Screw Spike Heads Estimated by FEM
(MDPI, 2021-11-15)
Railway spike screws are manufactured by hot forging on a massive scale, due to each kilometer of railway track needing 8600 spike screws. These components have a low market value, so the head must be formed in a single ...

In the current scenario of manufacturing competitiveness, it is a requirement that new technologies are implemented in order to overcome the challenges of achieving component accuracy, high quality, acceptable surface ...
Multi-Response Optimization of Abrasive Waterjet Machining of Ti6Al4V Using Integrated Approach of Utilized Heat Transfer Search Algorithm and RSM
(MDPI, 2021-12-15)
Machining of Titanium alloys (Ti6Al4V) becomes more vital due to its essential role in biomedical, aerospace, and many other industries owing to the enhanced engineering properties. In the current study, a Box–Behnken ...
Metamodels’ Development for High Pressure Die Casting of Aluminum Alloy
(MDPI, 2021-10-31)
Simulation is a very useful tool in the design of the part and process conditions of high-pressure die casting (HPDC), due to the intrinsic complexity of this manufacturing process. Usually, physics-based models solved by ...
A Rubric to Assess and Improve Technical Writing in Undergraduate Engineering Courses
(MDPI, 2021-03-24)
Although there is consensus in the literature that writing skills are important in STEM (Science, Technology, Engineering, and Mathematics) studies, they are often neglected. However, some efforts have been made to correct ...
Analysis of University STEM Students’ Mathematical, Linguistic, Rhetorical–Organizational Assignment Errors
(MDPI, 2021-04-06)
Although Error Analysis (EA) has been broadly used in Foreign Language and Mother Tongue learning contexts, it has not been applied in the field of engineering and by STEM (Science, Technology, Engineering, and Mathematics) ...
