Abstract
Transmission of a concentrated force into a half-infinite nonlocal elastic medium is examined. A nonlocal concentrated force boundary condition which is different from that of Nowinski is derived from the nonlocal principle. The nonlocal stress field is obtained analytically. The result eliminates the stress singularity which occurs in the classical stresses and also the nonlocal stresses derived by Nowinski. A theoretical cut-off strength Pc is discussed.
