Syllabus
To determine the Brinell Hardness number of Mild Steel and brass.
To determine the Rockwell Hardness number of Mild Steel and Hardened
steel specimens.
To determine the strength and other elastic and non-elastic properties of
mild steel, to observe the behaviour of the material under load and to study the
fracture as listed below:
1) Elastic strength in tension: (a) Modulus of elasticity
2) Non-elastic properties: (a) Upper yield point stress, (b) Lower yield point stress, (c) Breaking stress
3) Ductility: (a) Percentage elongation, (b) Percentage reduction in area
4) Nature of fracture
To study the impact strength properties of a brittle and a ductile material on
a Charpy Impact Testing machine.
To study the linearly elastic behaviour of mild steel under torsion and to
determine the shear modulus of elasticity, G. To study the complete behavior of mild steel under torsion and to determine
qualitatively the relationship between torsional load and angle of twist for a full range of strains till failure. 3. To determine whether the metallic materials fail in tension, compression, or shear when it is subjected to pure shear.
To determine experimentally the value of the rigidity modulus of the material of the
close coiled helical spring.
To determine the Young’s modulus of elasticity of (i) mild steel (ii) brass and (iii)
aluminium by beam deflection method.
To establish a relationship between the strut length and the buckling load and to compare
the results to the Euler theory
To test mild steel specimen in fatigue, plot S-N curve and obtain the
endurance limit.
Course Objectives
- The principal purpose of the hardness test is to determine the suitability of a material for a given application, or the particular treatment to which the material has been subjected. The ease with which the hardness test can be made has made it the most common method of inspection for metals and alloys
- Tensile Testing, also known as tension testing, is a destructive engineering and materials science test whereby controlled tension is applied to a sample either as a load for proof testing or until it fully fails. It is used to find out how strong a material is and also how much it can be stretched before it breaks
- The purpose of a torsion test is to determine the behavior a material or test sample exhibits when twisted or under torsional forces as a result of applied moments that cause shear stress about the axis
- To verify the Euler buckling load of a slender column for different end conditions
Course Outcomes
Student studies the behaviour of test specimens under different loading conditions, The mechanical properties of metals under different loading conditions are experimentally found, Verification of the same properties obtained from different tests are conducted,
