What are Important Material Properties in Mechanical Engineering?

05/02/2018 8:20 AM

Basically there are two types of materials i.e. metal and non-metal. The Mechanical properties associated with metals are:

1. Strength

The capacity of a material to withstand the load without failure is called strength. If a material can bear more loads, it means more strength. Strength depends on the type of loading and distorts before fracture.

2. Elasticity

The capacity of a material to regain its original dimension after removal of the load. The material is elastic material and the property is elasticity.

3. Isotropy:

A material with elastic properties along its all loading direction is called material.

4. Anisotropy:

A material exhibiting various elastic properties in the various direction of loads is called an-isotropic material.

5. Homogeneity

A material that retains properties throughout the geometry is called as homogeneous material and the property is called homogeneity. It is an ideal situation but the fact is that no material is homogeneous.

6. Plasticity:

The ability of a material to have some degree of permanent deformation without failure after removal of loads. The property is used for shaping material by metal working. It mainly depends on temperature and elastic strength of the material.

Having looked very closely it remains impossible to detect a question in the posting.

The title was a question.

The op must have had quite an epiphany.

...and its answer is in the posting.

<...epiphany...> Quite.

It is entirely dependant on the application... <simples>

There are several ways to interpret what you are looking for. One of them is differentiating three groups of properties:

1.- PHYSICOCHEMICAL PROPERTIES

2.- MECHANICAL PROPERTIES

3.- TECHNOLOGICAL PROPERTIES

1.- PHYSICOCHEMICAL PROPERTIES

The physical properties of metals are those that manage to change matter without altering their composition; like when you mold a piece of plasticine, its atoms are not altered from no way, but externally it changes its shape.

The chemical properties of metals are those properties that becomes evident during a chemical reaction (that there is a change); that is, any quality that can be established only by changing the chemical identity of a substance. The main ones, although not all, are:

.-Specific weight.• Melting point.• Specific heat.• Latent heat of fusion.• Dilation and contraction.• Extension.• Impenetrability.• Severability.• Inertia.• Resistance to oxidation.• Resistance to corrosion.• Aleability.• Pesantez.• Fluence.• Magnetism.• Electric conductivity.• Thermal conductivity.

2.- MECHANICAL PROPERTIES

The mechanical properties of metals are the inherent characteristics (typical of each metal), which allow differentiating one metal from another. From the point of view of mechanical behavior of metals in engineering, we must also take into account the behavior that a metal in the different machining processes you may have. We can distinguish the following mechanical properties of metals. The main ones, although not all, are:

• Hardness.• Tenacity.• Fragility.• Acritude.• Resistance.• Resilience.• Fatigue.• Elasticity• Plasticity.

3.- TECHNOLOGICAL PROPERTIES

These properties I think are what you are looking for. The technological properties of metals, is the behavior that these have when they are worked and studied by human beings. These properties allow us to differentiate a metal from another and know if the metal used is appropriate or not for the purpose it will play. We can distinguish. The following technological properties of metals, The main ones, although not all, are:• Ductility.• Malleability.• Machinability.• Weldability.• Templability •Forgeability.

Ah, no. Specifically, "... can be established only by changing the chemical identity of a substance. ..." is not compatible with the list of qualities you provided as examples. Most on the list require no change in chemical identity.

.

Also, several of your terms are not material properties or not names commonly recognized for such.

'Inertia' is not a property which might be used to distinguish between different materials samples of the same mass.

'Acritude, Aleability.• Pesantez.• Fluence.' are problematic for different reasons.

compressive strength, hardness, toughness, hardness, plasticity, ductility, elasticity are not mentioned.
