Analysis of Superheater Work Under Creep Conditions

Problems of Structural Optimization Under Creep Conditions

Optimal structural design under creep conditions, initiated over 20 years ago, brings a fairly larg~ variety of problems, interesting both from theoretical and engineering point of view. Existence of the time factor leads to optimization for a prescribed lifetime and the number of independent variables in governing equations increases by one. Practical importance is connected with design of met...

Adrenosympathetic overactivity under conditions of work stress.

Serial measurements of urinary adrenaline, noradrenaline, and 11-hydroxycorticosteroid excretion were performed on 32 healthy men under two conditions of work stress; piecework and work on assembly line. A statistically significant increase in adrenaline, noradrenaline, and 11-hydroxycorticosteroids was observed for piecework and assembly line workers compared with salaried and 'ordinary' worke...

Stress Analysis of Flight Vehicles under Flight Conditions

A method is presented for the stress analysis of flight vehicles under different flight conditions including gust and control surface deflection (or maneuver) using the governing equations of rigid-body motions and elastic deformations. The Lagrangian approach is used to derive the governing equations of motions. For this purpose, the basic equations of motions are derived in terms of potential...
