ABSTRACT

 

The magnitude of stress distribution as predicted by the simplified strength of material theory was compared with that predicted by the theory of elasticity and was checked by a proposed set of test problems using the finite element method.  Stress analysis was applied in this study to several practical problems, and a graphical comparison was made between stresses using the three methods of analysis.  Results showed that the magnitude of stresses depends on the choice o the theory used, and the difference in stresses using the three methods of analysis reflects the degree of approximation involved in each method.  For those problems where planes before loading remain plane after loading, the simplified strength of material theory provides adequate solutions.
