MATHEMATICAL MODEL OF THE STRESS-STRAIN STATE OF A BEAM WITH A VARIABLE SECTION WITH AN EFFECT OF "BOUNDARY LAYER"
The essence of this mathematical model consist in construction of the basic stress-strain state which is עיצוב הבית based on a new hypothesis of a vertical element and an additional stress-strain state of the regional flat deformation arising of close rigidly jammed edge.It gives the chance more exactly to estimate the strength of aircraft
