Destructive Testing

What is Destructive Testing (DT)?

• A method to evaluate the properties of a material, component or system by subjecting it to conditions that cause it to fail.

• A non-invasive testing method that ensures the integrity of a material without causing damage.

• A process of repairing and restoring a material to its original condition.

• A technique used to enhance the durability of a material by adding protective layers.

The primary purpose of destructive testing is to:

• determine the point of failure of a material or product

• assess the aesthetic qualities of a product

• evaluate the environmental impact of a product

• measure the efficiency of a production process

True or False: The tested sample is typically damaged or destroyed during the process of destructive testing.

• True

• False

What are the mechanical properties determined by destructive testing?

• Tensile strength, hardness, and impact resistance

• Color and texture

• Electrical conductivity

• Thermal expansion

What does Tensile Testing measure?

• The material's ability to absorb energy

• The material's deformation under stress

• How a material behaves under a pulling force until it breaks

• The material's resistance to indentation

Creep Testing determines a material's deformation under prolonged stress at ________.

• high temperatures

• low temperatures

• room temperature

• sub-zero temperatures

What is the property of a material to withstand compressive forces without breaking or crumbling?

• Tensile Strength

• Ductility

• Malleability

• Compressive Strength

There are no published standard values for shear strength like with tensile and yield strength.

• True

• False

The Mohs scale of mineral hardness is based on the ability of one natural sample of mineral to scratch another mineral visibly.

• True

• False

The hardness of a material is measured against the Mohs scale by:

• comparing it to a set of reference minerals

• using a hardness testing machine

• measuring its resistance to scratching

• determining its chemical composition
