Data for designers
DATA FOR DES/GNERS Intended for use by structural engineers in the construction industry is a new set of Data Items recently launched by Engineering Sciences Data Unit (ESDU). Entitled the Engineering Structures Sub-series, the data cover the following areas: buckling of plates, cylinders, struts and beams; plates under pressure, crack propagation and the fatigue strength of materials; and stress concentrations and the fatigue of welds. The Data Items themselves are produced from a wide variety of published and unpublished data taken from international sources. They are available in printed form and, increasingly, with related computer programs. Data are presented in the form of procedures, formulae and equations, tabulated and graphical data, and, where possible, worked examples. The Data Items are subject to constant review and revision, and thus the new Engineering Structures Sub-series is expected to grow as other areas of interest, such as residual stress effects, crack threshold values, fracture and fatigue behaviour in adverse environments and stress intensity factors, are dealt with. It is expected that the new Subseries will be of particular interest to those involved in projects such as refineries and petrochemical installations, bridges, tall buildings, offshore platforms and rigs; and for those involved in constructions containing welds and steel plates of various thicknesses. The Engineering Structures Subseries is priced at £240 f o r U K customers and £480 f o r those outside the U K ; f u l l details are available f r o m :

STRA IN GA UG ING Two new pieces of equipment for use with strain gauges have recently been made available by Hottinger Baldwin Messtechnik; the UMV 3052 measuring amplifier and the DMD 20 portable strain meter. The UMV 3052 is designed for use in multi-point transducer scanning systems. It has two separate and different amplifying channels: one for measurements with strain gauges and strain-gauge transducers; and the other for measurements with inductive

transducers. The DMD 20 is a high accuracy digital strain meter, designed to operate in the field with strain gauges and strain-gauge transducers. In conjunction with these it will measure and display properties such as force, pressure, strain, etc. Although designed primarily for measuring static quantities the DMD 20 can be used to record low frequency alternating phenomena by means of an analogue output signal.

Esin, published in the October 1980 issue. The composition of steel C10 is 0.095%C, not 0.9095%C as published. Apologies are due to the author and to readers for any confusion

Preview The following section contains details of some forthcoming events relating to fatigue and the wider aspects of metallurgy,
materials science and engineering. Items are arranged in chronological order. Further details can be obtained from the address given at the end of each item. A list of forthcoming events will also be found in the Calendar at the back of the journal.
A short course on Engineering fracture mechanics: numerical methods and applications is to be held at University College of Swansea, Wales on 6 - 9 April. The organizers have aimed the course at practising engineers and those working in research and development who require a better understanding of numerical techniques that can be used to solve fracture mechanics problems. Topics to be discussed will include existing standard methods of fracture prediction for industrial design; application of finite element methods to linear elastic fracture mechanics; exact field modelling by crack-tip elements; elasto-plastic finite element analysis and application to non-linear fracture; and industrial applications of numerical methods. Full details of the course can be obtained from: Dr A. R. Luxmore or Dr D. R. J. Owen, Department of
Civil Engineering, University College of Swansea, Singleton Park, Swansea SA2 8PP, Wales.
The National Association of Corrosion Engineers (NACE) in the USA will hold its 1981 Materialsperformance and corrosion show in Toronto, Canada, on 6 - 8 April. This will run concurrently with Corrosion 81, an international conference also organized by NACE. Full details of both events can be obtained from: the Conference
Co-Ordinator, NACE Headquarters, P.O. Box 218540, Houston, Texas 77218, USA.
Measurement of high temperature mechanical properties of materials is the title of a conference to be held at the National Physical Laboratory, Teddington, England, on 5 - 5 June. The meeting will concentrate primarily on those tests and measurement pro, cedures which, either now or in the future, provide - or are expected to provide - the design engineer or plant operator with quantitative material property data for high temperature applications. Expected topics for discussion include: material property requirements: standards; temperature measurement; design of uniaxial and multiaxial creep and fatigue test machines; strain and crack extension; environmental test facilities; and data
logging. Further information is available from: Malcolm S. Loveday, Division
of Materials Applications, National Physical Laboratory, Teddington, Middlesex TWI l 0LW, England. A call for papers has been issued by SAMPE (Society for Advancement of Material and Process Engineering) for its 15th National Technical Conference, to be held at Mt Pocono, Philadelphia, USA on 1 5 - 1 5 October. The overall conference theme will be 'Technology transfer' and papers are solicited for the following subject areas: composites - applied technology; polymer innovations; electronic and communications materials; processing chemicals - disl)osal and recycling; adhesive technology; energy production; reinforcements and fillers; and corrosion control. Intending authors are asked to submit 250 word abstracts by 1st February; completed papers will be required by 1 July. Abstracts should be submitted to: Dr Mike Michno,
