Bounds on the trace mappings defined on the Sobolev space View the MathML sourceW^{1,1}(Ω) and the space LD(Ω) of integrable strains are obtained. In the mechanics of continuous media, such bounds correspond to stress concentration--the ratio between the maximal stress in a body and the maximum of the traction applied to its boundary. The analysis leading to the bounds may be described in the mechanical context of stress theory and stress concentration.
