In particular a two dimensional plain strain elastic linear problem is described and solved by two different approaches. Smoothed Particle Hydrodynamics is a meshless computational scheme able to perform an integral representation of a function by means of a smoothing kernel function by involving a finite particle distribution in the discrete formulation. The first approach is derived by the variational formulation of the equilibrium equation, while the second one is a direct differential method. Numerical examples on the cantilever beam problem are implemented to verify and compare the proposed approaches.展开更多

Simply processing, remembering and applying the material learned from lectures and laboratory experiments With artificial criteria are inadequate. Hands-on teaching techniques with real-world problems are needed to complete the engineering students＇ education. This paper demonstrates how hands-on experiments performed in industry support and increase the students＇ understanding of fundamental principles and skill in their applications. Graduates with both knowledge and skill are more competitive in today＇s job market. A one-quarter industry-based vibration course was developed and taught with a hands-on segment at the Manufacturing and Mechanical Engineering and Technology （MMET） program at Oregon Institute of Technology （OIT） - Portland Campus. This novel instructional approach provided students with the opportunity to immediately apply material, learned in class and laboratory, in real-world industry situations with real-world problems. This instructional approach is applicable in many engineering fields and the author found the mechanical vibrations class particularly well suited for this instructional design style. The hands-on approach, grounded in the vibration course curriculum, provided a direct link to the fundamentals of vibration in industry. Student comments are included to demonstrate the value perceived by the students. Although this curriculum experiment involved mechanical engineering technology students, it would benefit mechanical engineering students equally well. In addition, the paper provides a brief description of the industries that participated in this project. Industries were selected because they use vibration based manufacturing, perform extreme testing or design their products to avoid failure due to vibrations.展开更多

Why is experience so important to employers？ Can students accumulate ＂working＂ experience while studying in college？ This paper discusses the use of design projects inside and outside of classrooms to help students gain ＂working＂ experience and skills through hands-on design activities that simulate the actual design activities that occur in the industry. Faculty members from the Mechanical Engineering Technology and Computer Engineering Technology departments were involved in creating multidisciplinary design projects. The design projects give students new insights into what they learn in their coursework and pro.vide students the valuable experiences in analytical skills, concurrent engineering approach, people skills, and management skills needed for the students when looking for employment.展开更多

The structure and functionality of the CBO （Brazilian Occupational Classification） 2002, fundamental tool for data analysis was used, followed by collection, diagnosis and data analysis to identify the characteristics and transformations of the occupational tasks of the electronic and mechanical engineer. The analysis was based on CBO data in three distinct steps described in the methodology section, compared with a study conducted in the early 1990s, and finally, the overall prevailing trend required in professional engineering training in times of complexity and in the knowledge era was presented.展开更多
