ANALYSIS OF THERMALLY LOADED LAMINATED CIRCULAR PLATES

THE INVESTIGATION IS CONCERNED WITH THE FORMULATION OF A METHOD TO DETERMINE STRESS LEVELS IN LAMINATED PLATE SYSTEMS, WHEN SUBJECTED TO THERMAL AND/OR MECHANICAL LOADINGS, FOR USE IN SIMULATION OF A HIGHWAY PAVEMENT SYSTEM. THE PHYSICAL PARAMETERS WHICH AFFECT THE STRESS ARE LISTED. PARAMETRIC INVESTIGATIONS ARE CARRIED OUT TO DETERMINE THE INFLUENCE OF THE INDIVIDUAL PARAMETERS ON THE TEMPERATURE-INDUCED STRESS LEVELS IN ONE-, TWO-, AND THREE-LAYERED PAVEMENT SYSTEMS. IN ADDITION, THE FORMULATION IS MODIFIED TO INCLUDE IN THE STUDY THE SIMULTANEOUS IMPLICATION OF MECHANICAL (WHEEL AND SUBBASE) AND THERMAL LOADINGS. RESULTS ARE OBTAINED FOR THE THERMALLY LOADED THREE-LAYERED SYSTEM WITH AND WITHOUT MECHANICAL LOADINGS TO DETERMINE WHEN AND HOW MUCH VEHICULAR TRAFFIC INCREASES THE STRESS LEVELS IN THE PAVEMENT PRESENT DUE TO A TEMPERATURE GRADIENT. TWO EXTREMES OF TEMPERATURE FIELDS ARE CONSIDERED: A) TEMPERATURE DISTRIBUTION ASSUMED TO DECREASE WITH PAVEMENT DEPTH AS AT MIDDAY IN WINTER; B) TEMPERATURE IN PAVEMENT IS INCREASED WITH DEPTH TO SIMULATE EARLY MORNING HOURS CONDITIONS. A SERIOUS PROBLEM IS ENCOUNTERED BECAUSE THE DEVELOPMENT OF SOPHISTICATED EXPERIMENTAL TECHNIQUES, TO MEASURE THE REQUIRED PHYSICAL PROPERTIES OF MATERIALS, HAS LAGGED BEHIND THE DEVELOPMENT OF MATHEMATICAL TOOLS TO MODEL AN EXISTING PAVEMENT SYSTEM.
