Conclusion:

The above given truss 3D truss has 05 nodes and 06 elements. In that node 1 and 2 has no degrees of freedom. Three equal loads were acting in the negative direction of y axis at nodes 3,4,5. Due to the loads the truss undergone deformation. In that maximum deformation was 47297.2mm at node 5. Element 2 has the maximum Stress value of 14560.7 N/mm2 and has maximum Strain value of 0.072804. Reaction force was acting on node 1 and node2 because of arresting the deformation. At node 1 reaction force at x, y and z axis were 5497.1, 2039.4 and 149.74 respectively and at node 2 reaction force at x, y and z axis were  -5497.1, 5460.6 and -149.74.

Quenching process

Quenching also called Hardening, is a heat treatment process in which steel is heated up to austenite temperature (above it's critical temperature), hold for some time and then cooled in water, oil or molten salt (rapid cooling). Due to rapid cooling, it results very hard structure - martensite (hardest form of Steel). fig.- steel component quench in oil. Due to hardening process hardness of steel increases and bitterness also increases. (brittleness increases hence hardened Steel nay not directly use). Quenching is always follow by tempering process. Due to rapid cooling in hardening process metal shape shrink, internal residual stresses are setup. That's the reason why hardening is follow by tempering.

Additive Manufacturing processes

  What is Additive Manufacturing? As the name suggests, Additive Manufacturing (also known as 3D printing) is a group of manufacturing techniques , which manufacture parts by adding successive layers of material with the help of computer control systems. Various materials that can be used in additive manufacturing (AM) are plastic, metal, concrete, also human tissue. In the additive manufacturing process, Computer-Aided Design (CAD) is created and utilized to manufacture 3-Dimension (3D) objects. Various CAD-CAM software is required to Design, Analyze, and Manufacture parts. Once CAD data is produced, Slicing software slices the design in different layers (as required by different  AM processes), and then data utilized to manufacture required material parts. Different terms like “3D printing” and “rapid prototyping” are also casually used to describe Additive manufacturing, but each one is a subset of additive manufacturing. Hence in the simple sense, Additive manufacturing te...

Case hardening (surface hardening) process

The case hardening process is used to harden the outer surface of the material, the inner surface of the material remains soft. hence this process is also called surface hardening. The type of case hardening process is as follows Carburizing Nitriding Cyaniding Carburizing In the carburizing process, specimens are heated beyond the upper critical temperature in sealed containers having an atmosphere of carbon (C). Heating is continued for 4 to 10 hours, depending upon the depth of penetration required. Hence, carbon diffuses into the surface layer. Nitriding The nitriding process is similar to carburizing, but instead of carbon (C), nitrogen (N ₂ ) is used as a hardening agent in nitriding. The nitriding process is carried out in the ammonia atmosphere. The nitriding process requires less temperature compared to carburizing but requires more heating time compared to carburizing. Cyaniding In the cyaniding process, sodium cyanide (NaCN) is used as a hardening agent. Hence both carbon (C...
