The article describes the study of porous meshed material mechanical characteristics using
a structural approach, which involves determining the mechanical properties on the basis
of the mesh geometric parameters (standard size), mesh quantity, mutual arrangement,
mechanism of plastic deformation and quality of structure-forming element consolidation.
It is shown that porous meshed materials made by diffusion welding after mesh chemical
treatment has the maximum interlaminar strength for a given mesh briquette design and
compression. The dependences for determining strength, plasticity and anisotropy of the
porous meshed material in the plane of the sheet under uniaxial and biaxial tension are ob-
tained. It is found that increasing the formability and weldability of sheet blanks is achieved
by reducing the strength anisotropy, plasticity and thermal conductivity. To reduce the ani-
sotropy meshes with square cells should be used, their number should be increased, the an-
gle between them should be reduced, and compression in the process of their solid-phase
coupling should be increased.
Keywords
: porous meshed material, anisotropy, strength, plasticity, deformation rate,
welding, sheet-metal forming.
