A CONTINUOUS MECHANIC APPROACH TO TEACH SOLID MECHANICS
|
|
Resumo :
|
GENERALLY, ENGINEERING STUDENTS HAVE BEEN TAUGHT MECHANICS OF SOLIDS
AND STRENGTH OF MATERIALS THROUGH A TECHNICAL THEORY BASED ON
ONE-DIMENSIONAL MODELS OF BARS AND BEAMS. BASIC CONCEPTS SUCH AS STRAIN AND
STRESS ARE DEFINED FOR SPECIFIC PROBLEMS WITH NO RELATION TO THE GENERAL
CASE. THEREFORE, STUDENTS DO NOT LEARN HOW TO APPLY THOSE CONCEPTS TO MODELS
THAT ARE COMMON IN REAL PROBLEMS SUCH AS PLANE STRESS, ELASTIC SOLIDS,
PLATES, AND SHELLS. STUDENTS ARE NOT ALSO ABLE TO LINK RELATED CONCEPTS
IN SOLID AND FLUID MECHANICS.
IT CAN BE SAID THAT STUDENTS HAVE MISSED A GOOD BACKGROUND IN BASIC
CONCEPTS OF MECHANICS. CONSEQUENTLY, THEY WILL NOT BE PREPARED TO USE
ENGINEERING SOFTWARE CONFIDENTLY. IN ORDER TO OVERCOME THIS LIMITATION,
STUDENTS SHOULD BE TAUGHT STARTING FROM THE BASICS CONCEPTS OF MECHANICS TO
ACQUIRE A STRONG BACKGROUND. MOREOVER, IT IS NOT POSSIBLE TO TEACH SPECIFIC
CONCEPTS WHILE THE APPLICATIONS OF MECHANICAL ENGINEERING HAVE DEMANDED
BACKGROUND IN MULTIDISCIPLINARY AREAS.
SOME EDUCATIONAL PROJECTS HAVE BEEN DEVELOPED TO ACHIEVE AN
INTERACTIVE COURSE IN FORMULATION AND NUMERICAL SOLUTION OF MECHANICAL
PROBLEMS. FOR THIS PURPOSE TWO BOOKS HAVE BEEN PREPARED BASED ON A CONTINUUM
MECHANICS AND VARIATIONAL FORMULATION APPROACH. INTERNET
HOMEPAGES, JAVA PROGRAMS, AND MULTIMEDIA APPLICATIONS HAVE ALSO BEEN
DEVELOPED. THE GENERAL OBJECTIVE IS TO PRESENT
ENGINEERING STUDENTS THE BASIC MECHANICAL CONCEPTS USING MULTIMEDIA AND
SOFTWARE RESOURCES TO SIMPLIFY UNDERSTANDING AND ASSIMILATION OF KNOWLEDGE.
THIS PAPER PRESENTS A REVIEW OF THE STATUS OF THOSE EDUCATIONAL PROJECTS.
KEYWORDS: CONTINUOUS MECHANICS, VARIATIONAL FORMULATION, JAVA, MULTIMEDIA, INTERNET.
