Cheat Sheet
- Understanding Tensile Strength and Stress-Strain Behavior -
The stress-strain curve illustrates elastic and plastic regions with stress = F/A and strain = ΔL/L₀, while Young's modulus E = σ/ε quantifies stiffness. Yield strength marks the onset of permanent deformation and ultimate tensile strength (UTS) is the peak stress before necking occurs. Use the mnemonic "EAR" (Elastic, At yield, Rupture) to recall these stages when tackling the engineering materials testing quiz.
- Comparing Rockwell, Brinell and Vickers Hardness Tests -
Rockwell hardness (e.g., HRC) measures penetration depth under a diamond cone or steel ball, Brinell (HBW) averages impressions from a large spherical indenter, and Vickers (HV) uses a diamond pyramid with HV = 1.854·F/d². Each scale suits different materials: high-hardness alloys (Rockwell), castings (Brinell), and thin samples (Vickers). Remember "RBV" (Rockwell, Brinell, Vickers) to breeze through materials testing trivia.
- Hall-Petch Relationship and Grain Boundary Strengthening -
The Hall-Petch equation σy = σ₀ + k·d❻½ relates yield strength σy to average grain diameter d, showing that finer grains boost strength by impeding dislocation motion. Grain refinement is a key strategy in metal processing, from forging to annealing. Think "Small Grains = Big Gains" when reviewing materials science quiz questions.
- Key Non-Destructive Techniques: Ultrasonic, Radiographic and Eddy-Current -
Ultrasonic testing uses wave reflection to detect internal flaws, radiography employs X-rays or γ-rays for imaging, and eddy-current testing senses surface cracks via electromagnetic induction. These methods preserve sample integrity, making them essential for safety-critical inspections in aerospace and infrastructure. Use the acronym "SEE" (Sound, X-ray, Eddy) to recall these NDT methods in your engineering materials quiz.
- Charpy Impact Test and Temperature Effects on Toughness -
The Charpy V-notch test measures energy absorption in a swinging pendulum impact, revealing ductile-to-brittle transition temperatures for steels. Plotting impact energy vs. temperature shows a sharp drop at the transition, critical for cold-climate applications. Mnemonic: "CVN at TV" (Charpy V-Notch at Transition Temperature) helps lock in this concept for your materials science quiz prep.
