Comparison of three- and four-point flexural strength testing of denture-base polymers

Dental Materials, 1989
Flexural failure of denture-base materials is considered the primary mode of clinical failure. However, there are several methods of conducting flexural tests, and none has been demonstrated to be the most appropriate. Three- and four-point bend-testing were compared, with four different dental polymers used.

Flexural strength of dental composite restoratives: Comparison of biaxial and three‐point bending test

Journal of Biomedical Materials Research Part B: Applied Biomaterials, 2004
AbstractThis study compared two test methods used to evaluate the flexural strength of resin‐based dental composites. The two test methods evaluated were the three‐point bending test4 and the biaxial flexural test. Materials used in this investigation were from the same manufacturer (3M ESPE) and included microfill (A110), minifill (Z100 and Filtek ...

Flexural strengths of conventional and nanofilled fiber‐reinforced composites: a three‐point bending test

Dental Traumatology, 2013
AbstractObjectivesThe purpose of this study was to evaluate the effect of the introduction of nanofillers on the mechanical properties of fiber‐reinforced composites (FRCs) for stabilization and conservative treatment of multiple traumatized anterior teeth. In particular, the aim of the research was to point out the force levels of two sizes (diameters

On the three-point flexural tests of dental polymeric resins

Bio-Medical Materials and Engineering, 1997
Currently acrylic resins are commonly employed in many medical applications, especially for the fabrication of long span provisional restorations in dentistry and bone cement in orthopedics. One of the major problems associated with the conventional type of acrylic resins is their unsatisfactory mechanical properties.

Flexural Behavior and Fracture Characteristics of Polymeric Pipes Under Curved Three-Point Bending (CTPB) Tests

, 2021
This study describes an investigation of the load-deflection response of polymeric pipe material. Three point bending tests were performed on curved samples extracted directly from the studied pipes to evaluate their flexural properties, namely the flexural strength, the modulus, the strain to failure, the stress intensity factor, the fracture energy ...

Model for estimating the flexural performance of concrete reinforced with hooked end steel fibers using three‐point bending tests

Structural Concrete, 2021
The behavior of fiber reinforced concrete (FRC) depends on the characteristics of both the concrete matrix and fibers. Previous studies have concluded that the number of hooked ends increases the contribution of steel fibers to the tensile performance of
