Fracture Energy Measurement in Different Concrete Grades

Fracture energy is regarded as an intrinsic (material) properties that dominates crack mechanisms and associated growth in concrete damage under applied stress. In recent times, significant advancements computing technology have driven the adoption of finite element analysis (FEA) methodologies necessitate integration constitutive models, includingthe traction-separation relationship derived from cutting-edge fracture mechanics. A physically-based model requires values; therefore, a properly measured value essential to exhibit better structure response within FEA models. There are large arrays parameters involved during mixture, such beam size effect, aggregate size, grade, affect flexural resistance concrete.
