چکیده
Concrete is a brittle material whose tensile strength about one-tenth of its compressive strength. Tensile key parameter for concrete under impact loading. When turning point occurs before peak load in the load–time curve from dynamic Brazilian disc test, there no basis choosing or to calculate The objective this study determining crack initiation stress at peak. method contrasts time duration Digital image correlation (DIC) and split Hopkinson pressure bar (SHPB) system order obtain value when cracking first appears. less than specimens with curve. equal without proposed successfully applied determine specimens.

Determination of Tensile Strength and Crack Growth of a Typical Polymer Concrete Using Circular Disc Samples
Cracked and un-cracked Brazilian disc specimens subjected to diametral compression were used for conducting fracture toughness and tensile strength experiments on a polymer concrete (PC) material. The value of mode I fracture toughness (KIc) was determined from the center- cracked Brazilian disc and the indirect tensile strength (σt) was obtained from the un-cracked Brazilian disc specimen. The...

متن کاملNew Approach towards Crack Determination in Concrete Using Upv Test
Nondestructive testing of concrete allows the inspection of larger areas of concrete members at lesser cost than coring and provides more information than visual inspection. This paper addresses a new approach for determining the positions and size of cracks in concrete members by using ultrasonic pulse velocity test. Three plain concrete beams, containing artificial cracks (30 – 60% of the bea...
متن کاملExtended finite element simulation of crack propagation in cracked Brazilian disc
The cracked Brazilian disc (CBD) specimen is widely used in order to determine mode-I/II and mixed-mode fracture toughness of a rock medium. In this study, the stress intensity factor (SIF) on the crack-tip in this specimen is calculated for various geometrical crack conditions using the extended-finite element method (X-FEM). This method is based upon the finite element method (FEM). In this m...
متن کاملCrack initiation in brittle materials
In this paper we study the crack initiation in a hyper-elastic body governed by a Griffith’s type energy. We prove that, during a load process through a time dependent boundary datum of the type t → tg(x) and in absence of strong singularities (this is the case of homogeneous isotropic materials) the crack initiation is brutal, i.e., a big crack appears after a positive time ti > 0. On the cont...
