Study on Thickness Effect of Three-Point-Bend Specimen

open access: yesJSME International Journal Series A, 2004
The thickness effect of three point bend (3 PB) specimen on dimple fracture behavior is studied experimentally and numerically. At first, fracture toughness tests were conducted using 3 PB specimens with different thicknesses. Fracture toughness values and R-curves are obtained and the thickness effect is discussed.

Innovative vibration technique applied to polyurethane foam as a viable substitute for conventional fatigue testing

open access: yesJournal of the Mechanical Behavior of Materials, 2012
Lifetime prediction using three-point bending (TPB) can at times be prohibitively time consuming and costly, whereas vibration testing at higher frequency may potentially save time and revenue. A vibration technique that obtains lifetimes that reasonably

Stress intensity factors computation for bending plates with extended finite element method [PDF]

open access: yes, 2012
The modelization of bending plates with through-the-thickness cracks is investigated. We consider the Kirchhoff–Love plate model, which is valid for very thin plates.
