Mechanical Testing Techniques Training Course

Thursday, 30th May 2019
The Jurys Inn, A5 Watling Street, Hinckley, LE10 3JA

Are you a manager or technician responsible for the testing of metals or metal components?
Are you interested in improving your knowledge of testing and test results interpretation?
Are you are a designer, specifier or work in a sales or purchasing environment?
This is the course for you!

Learning Objectives:
Understand the meaning of terms such as strength, ductility, hardness and toughness
Appreciate why compromise between high values of strength and toughness is necessary
Understand the metal structure differences between continuous and discontinuous yielding
Be familiar with parameters such as yield strength, proof stress, UTS, ductility measures and engineering stress-strain.
Distinguish between ductile, brittle and intergranular failures
Gain an insight into creep, fatigue and fracture mechanics

Agenda:

Section 1:

  • Introduction

Section 2: Tensile Tests

  • Tensile tests: parameters, sample preparation and types
  • Gripping methods: screw, wedge, hydraulic and pneumatic
  • Contact and non-contact extensometry
  • Continuous and discontinuous yielding; influence of metal structure
  • Further test parameters: engineering and true stress-strain, work hardening index

Section 3: Ductile, brittle and intergranular failure

  • Deformation of ductile metals
  • Brittle (or cleavage) fracture
  • Ductile-brittle transition
  • Crack propagation and crack arresting mechanisms
  • Intergranular fracture

Section 4: Hardness Tests

  • Hardness principles: Brinell, Vickers, Rockwell; indenters and test conditions
  • Relationship between hardness and grain size: Hall-Petch equation
  • Micro-hardness tests: Vickers and Knoop
  • Nano-indentation
  • Hardness conversion

Section 5: Pendulum impact tests

  • Toughness: a definition
  • Charpy and Izod test procedures
  • Sample types: full and sub-sized samples
  • Test results: ductile-brittle transition temperature
  • Role of microstructure
  • Charpy vs Izod

Section 6: Fatigue and creep testing

  • Fatigue in metals
  • Fatigue testing: axial loading and rotating bend test machines
  • Fatigue testing: stress-life (S-N), strain-life (ε-N) and
    fatigue crack growth rate (da / dN - ΔK) approaches
  • Stages of creep
  • Creep mechanisms: dislocation climb, Nabarro-Herring and Coble creep
  • Creep and stress rupture testing

Section 7: Fracture mechanics

  • Linear-elastic fracture theories
  • Fracture toughness tests: methods and sample types
  • Factors affecting toughness
  • Realm of application for different fracture mechanics theories; LEFM, EPFM etc.
