Numerical simulation of interlocking blocks under compression in Abaqus

In this tutorial, the Numerical simulation of interlocking blocks under compression in Abaqus has been done. The blocks are modeled as three dimensional solid parts with interlocking surfaces. You can see a figure of the assembled parts below

Masonry structure is one of the most predominant structures throughout the world particularly for low-rise residential structures. This is mainly because of its relatively low cost comparing with reinforced concrete and steel structures, outstanding thermal and sound insulation performance, and robust structural performance in comparison to timber and other structures. Conventional masonry construction comprises of clay bricks bonded together by a layer of mortar or cementitious material. Because of the relatively low strength of mortar, failure in conventional masonry structures always initiates in the mortar or at the bonding interfaces with bricks. Conventional masonry struc-tures normally exhibit poor structural performance particularly against extreme loading conditions such as earthquake, impact and blast loads.The interlocking mechanism can be provided in either horizontal,
vertical or both directions. The interlocking of blocks can improve the resistance of them againt the load

The Concrete Damaged platicity is used for the blocks to define the compressive nad tension behaviour. The model is a continuum, plasticity-based, damage model for concrete. It assumes that the main two failure mechanisms are tensile cracking and compressive crushing of the concrete material. The dynamic explicit step is appropraite for this type of analysis. The cohesive interaction by  defining the the stifness, damage, and its evolution is selected, by this way, the moret between the blocks is defined. The fixed boundary condition is assigned to the bottom rigid plate and the load is applied to the top rigid body witha smooth step amplitude to apply the smooth load. The mesh should fine to obtain the good results

After the simulation, all results are obtainable, you can see some the them below
