Abstract
The bending of beams supported by an elastic medium is analyzed using photoelasticity. Four models were considered: (1) A model representing a beam of infinite length with a concentrated control load; (2) a finite beam with a central load; (3) a finite beam with a load at the quarter point; and (4) a finite beam with two concentrated loads at the two quarter points. The bending moments, shears and contact pressures were obtained and compared with corresponding values for beams resting on a Winkler-type foundation. Several alternative ways of determining the pressure distribution at the surface of contact are presented. The analysis includes the stress distribution in the elastic medium.
