Strength of Materials II

Base Knowledge

It is intended that students have knowledge about the stability of structures subjected to bending stresses. Know how to calculate tangential stresses (shear stress) due the bending. And calculate efforts and stresses due to oblique bending, eccentric loading, composite bending in three-dimensional structures.

Teaching Methodologies

In theoretical classes, a theoretical exposition of each subject is made, which is complemented by the presentation of application exercises. Theoretical-practical classes mainly focus on solving exercises.

Learning Results

The objective of this course is to provide students with practical and simple methods for calculating the most common typical elements in structures, using several approximate calculation processes.

This U. C. allow students to obtain displacement in structures subject to flexion as well as select the normalized I profile. It gives knowledge of oblique flexion, eccentric load, deflected flexion. Know how to analyze three-dimensional and buckling structures
