23rd International Conference on Modelling in Mechanics 2025 Parametric analysis on concrete cone failure Lucie Malíková a,b, *, Petr Miarka a,b a Czech Academy of Sciences, Institute of Physics of Materials, v. v. i., Žižkova 513/22, 616 00 Brno, Czech Republic b Brno University of Technology, Faculty of Civil Engineering, Institute of Structural Mechanics, Veveří 331/95, 602 00 Brno, Czech Republic Abstract A cast-in steel anchor embedded in concrete and subjected to tensile loading was investigated numerically in order to assess basic features of the very common kind of failure, which is concrete cone failure. An idea based on the maximum tangential stress criterion was utilized and stress distribution at the anchor’s corner was analyzed at various critical distances. The influence of selected geometrical parameters, such as the anchor’s embedment length and its outer radius, was discussed. The conclusions obtained within this work enable to improve the design of the anchored concrete structures by means of suggestion of more advantageous dimensions of the anchor. A suitable choice of the geometrical parameters can decrease the value of the angle where the maximum of the tangential stress occurs and where the crack initiation is assumed. Thus, the initiated crack needs to overcome a longer path through the concrete specimen towards the specimen surface, which increases the resistance of such structures. © 2025 The Authors.

Introduction Anchors are often used to attach steel elements to supporting concrete members in order to transfer external loading to the concrete structure. Anchors can be distinguished according to the type of their installation to post installed and cast-in. The weak element of such a structure is almost exclusively concrete which can fail under tensile or shear loading. This paper is devoted to concrete cone failure which typically occurs under tensile loading 23rd International Conference on Modelling in Mechanics 2025 Parametric analysis on concrete cone failure Lucie Malíková a,b, *, Petr Miarka a,b a Czech Academy of Sciences, Institute of Physics of Materials, v. v. i., Žižkova 513/22, 616 00 Brno, Czech Republic b Brno University of Technology, Faculty of Civil Engineering, Institute of Structural Mechanics, Veveří 331/95, 602 00 Brno, Czech Republic Abstract A cast-in steel anchor embedded in concrete and subjected to tensile loading was investigated numerically in order to assess basic features of the very common kind of failure, which is concrete cone failure.
