摘要：
The article deals with asymptotic and variation methods of calculating weight functions. For multiparameter configurations a system of equations was obtained which makes it possible to calculate stress intensity factors for any load from solutions obtained for one or several reference loads, without solution of a boundary-value problem. It is shown that the use of the method of linear springs is effective in the calculation of weight functions.
