Experimental and Numerical Analysis of Fracture Processes in Concrete

摘要

In practice, structures made of concrete are full of cracks. The strength ofconcrete is mainly determined by the tensile strength, which is about 10% of the compressive strength. Because of this, reinforcement (mostly steel) is used to increase the carrying capacity of the material and to control the development of cracks if concrete is loaded in tension. However for designing concrete structures, knowledge is required about the strength of the concrete material and about the process of fracture growth that takes place in the concrete. In the chapter the subject of this research, which deals with a particular part of fracture research in concrete, will be clarified. Furthermore a short summary of the contents of the report will be given.
