“…The local mass matrix of a 3D beam element is implemented according to Equation (9) to Equation (14), where E is the material Young's modulus, G is the material shear modulus, S A is the cross-section effective shear area, I is the crosssection moment of inertia, and J is the cross-section polar moment of inertia. The matrix is decomposed into an Euler-Bernoulli component, EB e M , and a Timoshenko component, Tim e M .…”

This paper introduces a new version of the open-source educational software, LESM (Linear Elements Structure Model), developed in MATLAB for structural analysis of one-dimensional models such as frames, trusses, and grillages. The updated program includes dynamic analysis, which incorporates inertial and damping effects, time-dependent load conditions, and a transient solver with multiple time integration schemes. The software assumes small displacements and linear-elastic material behavior. The paper briefly explains the theoretical basis for these developments and the reorganization of the source code using Object-Oriented Programming (OOP). The updated Graphical User Interface (GUI) allows interactive use of dynamic analysis features and displays new results such as animations, envelope diagrams of internal forces, phase portraits, and the response of degrees-of-freedom in time and frequency domain. The new version was used in a structural dynamics course, and new assignments were elaborated to improve students' understanding of the subject.

“…Previous studies have reported on the use and benefits of mobile learning for students' performance and motivation in K-12 education [26,47]. Moreover, examples of mobile learning tool development and use within several engineering disciplines, including acoustics and vibrations [48], computer science [36], and structural dynamics [44], signal emerging acceptance of mobile learning within postsecondary engineering education. Although we found that available literature related to the development of mobile PIV learning tools for fluid mechanics education was limited (we did not find any in our search), our literature search did reveal work related to the development of a mobile PIV tool for the industrial fluid mechanics application of measuring surface flows (i.e., of rivers and discharges) during extreme weather events such as floods [10].…”

A robust and intuitive understanding of fluid mechanics-the applied science of fluid motion-is foundational within many engineering disciplines, including aerospace, chemical, civil, mechanical, naval, and ocean engineering. In-depth knowledge of fluid mechanics is critical to safe and economical design of engineering applications employed globally everyday, such as automobiles, aircraft, and sea craft, and to meeting global 21st century engineering challenges, such as developing renewable energy sources, providing access to clean water, managing the environmental nitrogen cycle, and improving urban infrastructure. Despite the fundamental nature of fluid mechanics within the broader undergraduate engineering curriculum, students often characterize courses in fluid mechanics as mathematically onerous, conceptually difficult, and aesthetically uninteresting; anecdotally, undergraduates may choose to opt-out of fluids engineering-related careers based on their early experiences in fluids courses. Therefore, the continued development of new frameworks for engineering instruction in fluid mechanics is needed. Toward that end, this paper introduces mobile instructional particle image velocimetry (mI-PIV), a low-cost, open-source, mobile application-based educational tool under development for smartphones and tablets running Android. The mobile application provides learners with both technological capability and guided instruction that enables them to visualize and experiment with authentic flow fields in real time. The mI-PIV tool is designed to generate interest in and intuition about fluid flow and to improve understanding of mathematical concepts as they relate to fluid mechanics by providing opportunities for fluids-related active engagement and discovery in both formal and informal learning contexts.

“…To date, computer‐aided educational platforms have been widely implemented in engineering courses to facilitate the teaching and learning process. Sonparote and Mahajan [30] developed a platform to demonstrate structural dynamics using JAVA [15]. A platform software prepared in the DELPHI environment was developed by Gencer and Gedikpinar [16] to be utilized in laboratories of electric machinery courses.…”

This study presents a computer‐aided educational platform, namely, ErosSSA (Eros‐Slope‐stability‐analysis) developed by the geotechnical group in the Hong Kong Polytechnic University, to provide civil engineering students and young industrial engineers a better understanding of the analysis of slope stability. The platform is developed under the MATLAB environment, with a clear framework and a graphical interface. Using this platform, the rotational landslides can be generally analyzed, considering a circular slip surface and the factors of safety defined with respect to basic and advanced methods with different force and/or moment equilibrium. Furthermore, the minimum factors of safety of different methods for a given slope can be determined. From the practical teaching of the ErosSSA in two courses for Bachelor and Master students, it was found that they were highly satisfied with the accuracy, reliability, and convenience of the ErosSSA according to their feedbacks to a questionnaire. These practical teaching experiences support the ErosSSA to be widely used as a suitable teaching platform in geotechnical engineering.
