Plastic Bending of Beams

This product helps students to understand the nature of plastic deformation and collapse in hot-rolled mild steel beams that can undergo large plastic deformations. This material is often used as a construction material in supporting beams or ‘rebar’ to reinforce concrete sections.

Learning Outcomes

  • Elastic bending to plastic deformation of hot-rolled mild steel
  • How the plastic region moves through the specimen section as the load increases
  • Collapse load and the formation of plastic ‘hinges’
  • Yield stress
  • How beam fixings affect deformation of:
    • simply supported beams
    • fixed or ‘encastre’ beams
    • a propped cantilever
  • Shape of a collapsed beam due to hinge formation
  • Form or shape factor of a beam and the additional factor of safety it provides

Key Features

  • Selectable beam fixing conditions, for increased experiment range
  • Includes a set of specimen beams for ‘out of the box’ experiments
  • Additional pack of specimen beams available
  • Industrial, high-resolution digital deformation indicator for maximum measurement accuracy
  • Includes Vernier caliper for beam cross-section measurement
  • Supplied with a storage tray to keep smaller items safe
  • Works with user-friendly software (VDAS®)
