SIMULATION OF STRAINING THE PLATE WITH ELASTIC EXTENDED
INCLUSIONS BASED ON FINITE ELEMENT METHOD
Gudramovich V. S., Gart E. L., Strunin K. A.
The research aim is to study numerically the stressed-strained state of rectangular plates with arbitrarilyoriented
extended
inclusions
(strip
ones
with
and
without
twists
at
ends)
depending
on
the
combination
of
rigidities
of inclusions, theirs sizes and orientations, relations of rigidities of inclusions and the plate. The research
method is the finite-element method in the form of the ANSYS standard licensed package. The following results
are obtained: the effects of the relation of rigidities of inclusions and the plate (matrix), their sizes, mutual orientations
of inclusions on distribution of stresses and strains over a wide range of materials (the paper deals with
aluminium and its alloys, steel, copper as examples) are analyzed. Plots of distributions of stresses intensities are
built. Two inclusions in the form of strips and ones with rounding at ends are examined. Algorithms for calculating
allow
consideration
of
the
stressed-strained
state
with
variations
in
characteristics
of
extended
inclusions,
their
forms,
quantities as well as relations of rigidities of inclusions and the matrix over wide range of rigidities. The
analysis made is of scientific and practical use for modelling processes in powder metallurgy and ceramics production,
deforming
the
media
with
discrete
variations
in
the
structure
and
structural
members
with
thin
straps
and
inclusions.
