Engineering & design department
Aurock is an engineering company specialized in the finite elements calculus applied to the mechanic and the thermic of the structures. The engineering and design department is expert in the behavior of brittle ceramic materials and also the damage behavior of materials like refractory castable. This skill allows structures sizing of big parts taking into account scaling effects specific to these materials.
Before manufacturing, Aurock brings you an assistance for the design and the the sizing of ceramic parts. Aurock takes into account the mechanical behavior specificities of these materials, for instance, the failure probabilistics effects that determine the maximum stress allowed. The use of these advanced models will guaranteed the mechanical structures behavior. Aurock can also help you in the failure analysis of refractory structures by studying the type of material used and could propose a new structure design.
