Micromechanical voxel unit cell for strength analysis of fiber reinforced plastics
نویسندگان
چکیده
For the strength analysis of unidirectional laminae an unit cell approach is illustrated. The unit cell is modeled with an approximate voxel mesh instead of a conventional mesh. Strengths are determined with continuum damage mechanics. A fracture energy formulation is applied to alleviate mesh dependency in the softening behavior. For direct loads the unit cell shows good capabilities for the prediction of strengths.

A micromechanical model is constructed for the compressive strength of fiber-reinforced cementitious composites (FRCs). This model is based on the classical models of compressive failure of brittle solids in which sliding microcracks induce wing-crack growth under compression loads. The concept of increased microcrack sliding resistance and wing-crack growth retardation associated with fiber br...

متن کاملStepwise Regression for shear capacity assessment of steel fiber reinforced concrete beams
The addition of steel fibers into concrete improves the postcracking tensile strength of hardened concrete and hence significantly enhances the shear strength of reinforced concrete reinforced concrete beams. However, developing an accurate model for predicting the shear strength of steel fiber reinforced concrete (SFRC) beams is a challenging task as there are several parameters such as the co...
