XCV111 Annual Report of the Delegacy of California Berkeley where he gained an insight into the American approach to research Members of the Civil Engineering department continued to play an active and influential part in professional and scientific committees outside the College They served either as members or in some cases as Chairmen of bodies such as the Council of the Institution of Civil Engineers and some of its committees the British Geotechnical Society the Materials Technology Divisional Committee of the Concrete Society Technical Committee of the British Standards Institution the Materials Research Committee of the Cement and Concrete Association the Training Consultative Committee for the Cement and Concrete Industry and committee of the American Concrete Institute Additionally they acted as members of editorial advisory boards for for the scientific journals Nuclear Engineering and Design Geotechnique and the Magazine of Concrete Research These public and voluntary duties make demands on time and energy but they are extremely valuable in maintaining live contact between the department and the wider world of industry Research continues into the creep of concrete under multi-axial states of stress and on the migration of moisture in massive concrete sections subjected to temperature gradient Further significant results have been achieved in the analyses of temperature effects and on the dis- placements and stresses in concrete structures In the field of continuum mechanics research is being pursued into problems of contained plastic deformation of soil and the effect of consolidation and into problems concerning randomly non-homogeneous elastic media Work con- tinues on air entrainment into water flow and self-priming spillway siphons Other studies are concerned with the economics of water supply and transient flow in hydraulic systems The department con- tinues to benefit from the stimulating contact of our Visiting Professor of Civil Engineering Professor de Josselin de Jong and from lectures by distinguished practising engineers who willingly give our students an insight into the profession they are about to enter new and interesting development was the signing of an agreement between the British Internal Combustion Engine Research Institute and the Mechanical Engineering department in order to achieve mutually beneficial co-operation in the fields of research and higher study Some pooling of resources was agreed and exchanges between the two establishments have already proved profitable Much is hoped from
