Hardness Measurement: indentation evidence in Materials

Students use the Materials remote lab to compare Vickers and Brinell hardness evidence, connect indentation size with hardness, and distinguish surface hardness from toughness or tensile strength.

• Explain hardness as resistance to localized plastic indentation.
• Compare Vickers and Brinell methods at an introductory level.

Includes student questions and response prompts.

Microstructure Analysis: controlled metallography images

Students use the Materials microstructure route to compare etched and non-etched images, section orientation, magnification, focus, and brightness, then connect microstructure observations to mechanical-property hypotheses.

• Explain why polishing, etching, section orientation, and magnification affect microstructure visibility.
• Use Materials microstructure controls to compare images systematically.

Includes student questions and response prompts.

Notched-Bar Impact Testing: toughness and fracture evidence

Students use the Materials remote lab to observe notched-bar impact tests, connect absorbed impact energy with toughness, compare treatments, and interpret fracture surfaces cautiously.

• Explain why notched-bar impact tests are used to compare toughness.
• Use impact-test video/result evidence to compare material treatments.

Includes student questions and response prompts.

Tensile Testing: strength and ductility from a real materials lab

Students use the Materials remote lab to observe a tensile test, interpret force-displacement evidence, identify elastic and plastic regions, and compare strength and ductility without inventing unsupported material data.

• Explain what a tensile test measures and what it does not measure by itself.
• Identify elastic response, plastic deformation, maximum force, and fracture from lab evidence.

Includes student questions and response prompts.
