he calculations were done for the elastic semi-strip ( G

that the values of the normal stress at the lateral side x 0  decrease to zero with the increasing of the distance from the semi-strip’s edge. When the semi-strip’s side is a 10  . A similar situation is observed during the analyses of the stress y x ,     when the semi-strip’s side is a 50  (Fig.4) and a 100  (Fig.6). At Fig.3 one can admit that the absolute values of the normal stress y  at the line   x a y / 2, 0;10   are higher by its absolute value then normal stress x  when the semi-strip’s side is a 10  . A similar situation is observed during the analyses of the stress y x ,   when the semi-strip’s side is a 50  (Fig.5) and a 100  (Fig.7). As it is seen the stabilization of the stresses y x ,   is observed when the semi-strip’s side is a 50  (Fig.5) or a 100  (Fig.7). y y x x P / , P /        
