John Brand Martin, South African civil engineer (Durban 20 April 1937 – Cape Town 07 October 1999) With P. Symonds his works on mode approximation techniques are today regarded as milestones in the history of plasticity theory Discovered simple theorems for obtaining upper bounds on the displacements in an impulsively loaded structure, and lower bounds on the duration of the response OTHER CONTRIBUTIONS /BIBLIOGRAPHY With S.
