The elastic stress field and small-scale yielding behavior of a bimaterial plate are studied for the case when surface traction is free in the vicinity of the bonding edge. It is shown that the elastic singular fields at the bonding edge can be classified into three types depending on the combination of elastic properties and bonding angles, i. e. the characteristic equation determining the strength of the singularity has (1) one real value, (2) two real values and (3) complex value. Suitable expressions of the singular stress field which are consistent with those of crack problems are presented. Finite-element analyses have been performed and features of the stress distribution and shape of plastic zone are discussed for each of the three cases
