COMPUTER AIDED SOLUTION IN AN APPLIED ELASTICITY EDUCATIONAL CASE STUDY - STATICALLY INDETERMINATE SYSTEM OF BARS

摘要

Most of the real structures are statically indeterminate and they cannot be analytically computed by simply applying the equilibrium conditions. This is why students must possess the appropriate knowledge to approach this type of problems, a first solution being based on analytic methods. The paper presents a case-study regarding the use of the Mohr-Maxwell method to conceive a solution which, once implemented, it can be used to solve a series of educational models. The original software application has many parameters and it can be easily used by the professor in order to solve the indeterminacy for other structures which have a similar or simpler shape. Moreover, using the specific attributes of the symmetrical and anti-symmetrical structures and applying the superposition principle, several other problems may be solved. The original software was developed in MINGW using ECLIPSE and it consists of 1100 computer code lines for the basic modules and for the case studies solved, until now.
