Tensile, shear, double cantilever beam (DCB) and axial crush box specimens from different lay-ups were made and tested under quasi-static conditions to determine the mechanical properties, interlaminar fracture toughness (GIC and SEAA.
Therefore special box specimens were designed with a representative radial stiffness similar to that of large diameter connections, with both full size grout thickness and geometry of the shear keys.
The double cantilever beam (DCB), three-point-end-notched flexure (3ENF) and axial crush box specimens were fabricated from carbon/epoxy twill weave fabrics of [0]4, [45]4 and [0/45]2 and they were tested under quasi-static condition to determine the interlaminar fracture toughness in Mode-I (GIC), Mode-II (GIIC) and SEA of each lay-up.
Upto design load, segmental box girder specimen with dry and epoxy joints behaved like monolithic beam.
He began to race around again, and before long his arms were filled with a box of specimen jars, the hula hoops, a net, a hammer, a rope, a worn leather briefcase that was only half buckled, and several rolled-up maps.
The Specimen Box is a clear physical box with a tracking component which, when in the environment, appears to house virtual content.
Boxes of specimens and matrix suffered water damage.
Both welded I- and box-section specimens are considered.
Laboratory fatigue tests were designed and conducted to study the propagation of shear diagonal crack of PC box-girder specimens under cyclic loadings.
By reviewing documentation related to the boxed faunal specimens in the Hearst, the student will help us prioritize analysis of the assemblages based on those which have the best provenience and documentation.
