ITW Structural and Strength of Materials
Teaching Laboratory

Civil & Materials Engineering


November 2009

Laboratory Needs

Introductory Strength of Materials, Properties
of Materials, and Structural Analysis Courses
are presently offered without laboratory

These courses are taken by over 600 students
per year

Space is available for the laboratory, and a
new faculty member qualified to supervise the
labs will join UIC in Spring 2010


Universal Testing System for

Basic Concepts

Metallic, Cementitious and Composite materials

Important in all basic materials and structures courses

Testing System Requirements for Basic Concepts

Universal Testing Machine

Capability for tension , and compressions tests with load capacities of up to 300 to 500 Kips to
accommodate compression testing of concrete cylinders

Tensile grips and compressions platens for testing of metallic and cementitious materials

Stiff frame for control and accurate measurement of displacements

Fixtures for shear tests either direct or torsion

Flexure test grips fixtures

Environmental test chamber for simultaneous mechanical and

thermal loading of specimens

High capacity silent flow pump for static and fatigue testing of specimens

(25 gpm or higher)

Software for control of test parameters

Testing of Materials under High Rates of Loading

Impact Tests

Testing System Requirements for Impact Tests

Drop Weight Impact Testing System

High impact energies (20,000 joules or higher) for testing of a variety of materials
including concrete, steel, and fiber reinforced polymer composites

High impact velocities , i.e. 15
20 ft/s

Support fixtures for mounting and fixing the specimens

Test control software
