Measures of Dispersion
If everything were the same, we would have no need of statistics. But, people's heights, ages, etc., do vary. We often need to measure the extent to which scores in…
Measures of Central Tendency
The term "Average" is vague Average could mean one of four things. The arithmetic mean, the median, midrange, or mode. For this reason, it is better to specify which average…
Frequency Polygon
The relevance of presentation of data in the pictorial or graphical form is immense. Frequency polygons give an idea about the shape of the data and the trends that a particular data set follows. Let us…
Graphs and Histogram
What is a histogram? These are a diagrammatic representation of data. The use of tabular data and graphs and charts makes it easy to understand the concept of bar charts and histograms. In…
Finite Element Analysis of Plate and Shell Structure
The plate and shell structure is a structure in which the dimension in the thickness direction is much smaller than the size in the length and width directions. Among them,…
Plane Stress Elements
They must be plane, i.e., the coordinates of the element nodes must be in one flat plane, the xy plane of the element. They must be thin, i.e., the thickness t must be small in relation…
Plane Stress Condition
2 Dimensional States of Stress and Strain Principal Stress and Principal Plane Stress-strain Relationship for Isotropic Materials (in Plane Stress condition)
Forms of structure (beam,trusses arch and frames) in structure analysis
FORMS OF STRUCTURES Any civil engineering structure is conceived keeping in mind its intended use, the materials available, cost and aesthetic considerations. The structural analyst encounters a great variety of…
ONE DIMENSIONAL ELEMENT
Bar and beam elements are considered as One Dimensional elements. These elements are often used to model trusses and frame structures. Bar is a member which resists only axial loads.…
