For adhesive bond, it can be distinguished between specificand mechanical adhesion. The specific adhesion is generally influenced by physical and chemical interaction on molecular level. The mechanical adhesion occurs due […]

In the splitting test, a cylinder is loaded in compression on two diametrically opposite pads. The concrete is in a biaxial (compression-tension) state of stress and tensile failure occurs on […]
EK567
The modulus of rupture is the maximum tensile stress reached in the bottom fibre of the test beam and calculations are based on elastic theory. Stress is assumed to be […]
EK566
In the modulus of rupture test, a simply supported beam is tested with either central point loading or third point loading.

Elastic materials are ideal materials that return to their original configuration on unloading and obey Hooke’s law.
EK480
Isotropic means the material properties are the same in al directions, and also the loadings are the same in all directions.
EK476
A material is regarded as being tough if it absorbs a large amount of energy in breaking.
EK475
The ductility of a material describes the amount of deformation that precedes fracture.
EK474
Diffusion-controlled creep: A tensile stress increases the separation of atoms on grain boundaries that are normal to the stress axis, and the Poisson contraction decreases the separation of atoms on […]

Several mechanisms may contribute to creep. These include viscous flow, diffusional flow, and dislocation movement. Viscous flow is the dominant mechanism in amorphous materials.
