In Finite Element Design of Concrete Structures: practical problems and their solutions the author addresses this blind belief in computer results by offering a useful critique that important details are overlooked due to the flood of information from the output of computer calculations. Indeed, errors in the numerical model may lead in extreme cases to structural failures as the collapse of the so-called Sleipner platform has demonstrated.

A study has been conducted at Hong Kong Polytechnic University to develop a procedure to better predict long-term performance of asphalt concrete pavements. To achieve this end, complicated finite element techniques are employed and parametric studies are performed. The fatigue destructive mechanics (fracture mechanics and damage mechanics) are used to develop a 3D Finite element model that can be applied to characterize the nonlinear properties of the asphalt concrete materials. A set of materials tests is preformed to evaluate various bituminous wearing course materials by using Universal Servo Pneumatic Testing System in Hong Kong Road Research Laboratory such as indirect tensile modulus, dynamic creep, indirect tensile fatigue and wheel tracking. The materials for this study comprise conventional asphalt concrete wearing course (ACWC) and stone mastic asphalt (SMA) with a virgin 60/70 bitumen and different modified bitumen (Polypropylene, Crumb rubber, Cellulose fiber, Asbestos fiber and Gilsonite). The test results are analyzed in a multiple regression technique to capture the parameters in the proposed creep model. With the developed materials models, the typical flexible pavement structures are modeled in the finite element software, ANSYS. The real vehicle loads are employed and the effects of the footprint shape, loading frequency, and curing time are studied by using this computer simulation technique. The simulation results show that the SMA has a better healing effect and a longer micro-damage fatigue life than other mixtures with significantly enhanced healing effect. In addition, after the fatigue analysis and the prediction of the service life of flexible pavement, a sensitivity analysis is conducted to investigate the effect of cross section and load attributes factors on pavement response.

This report examined current computerized analysis techniques for slabs on grade. The focus of investigations presented is the application of the three dimensional finite element program GEOSYS for the analysis of a slab, resting on a stress dependent elastic solid foundation. This model can be used to establish baseline structural response data, representative of complex boundary and support conditions, thereby validating conclusions reached on the basis of two dimensional analysis. Many computer runs were conducted to develop user guidelines for the fruitful utilization of the three dimensional approach. Effects considered include mesh fineness and gradation, subgrade extent, boundary conditions, etc. The three fundamental loading conditions, viz. interior, edge and corner, are examined. Two typical single and multi-wheel U.S. Air Force aircraft are employed (F-15 and C-141). Anm iterative scheme is introduced to account for subgrade stress dependence. The effect of stress softening, typical of cohesive soils, is evaluated and discussed. A number of interesting observations are made, and their bearing on current analysis and design approaches is considered. Two broad areas for future research are identified. The relevance and need of the GEOSYS model to future pavement research/development activities is established. Keywords: Runway Pavements; Slab Model.
