Effect of inorganic chalk additive on 3D-printed polylactic acid specimens

Abstract This work examines the influence of an inorganic chalk-based additive on the quality and mechanical properties of products produced by 3D printing using the fused filament fabrication (FFF) method from polylactic acid (PLA). The use of inorganic additives is common mainl...

Supersonic turbulent boundary layer under conditions of distributed positive air mass transfer through a permeable surface

The paper presents experimental study on efficiency of controlling a supersonic turbulent boundary layer on a flat surface by positive-directed air mass transfer via a finely perforated wall. Experiments were performed for a flow with Mach number 2 and the unit Reynolds number eq...

Dynamic Resistance of Heterogeneous Metal–Ceramic Plates with Pyramidal Inclusions

Abstract Numerical simulations were performed to investigate the response of a finite–thickness metal–ceramic plate with a periodically arranged pyramidal mesostructure under impact by a penetrating rod projectile. The plate was fabricated from an aluminum (Al)–matrix composite r...
