Damage Evolution and Delamination Resistance in Polymer Matrix Functionally Graded Laminates
Abstract: Functionally graded laminates (FGLs) in polymer-matrix systems represent a promising pathway to enhance damage tolerance and delay delamination in advanced structural composites. In this study, we explore the mechanisms of damage initiation, propagation, and delamination resistance in polymer matrix functionally graded laminates (PM-FGLs) through a combined experimental–computational approach. Laminates with linear, exponential, and bio-inspired gradation profiles were fabricated using vacuum-assisted resin transfer molding (VARTM) and additive manufacturing techniques. Comprehensive mechanical …

Monitoring and Forecasting in Construction Projects Using Time Buffer
Abstract: The key to project management is effective performance monitoring and forecasting. The existing methods using input- output cash flow, earned value, etc. do not differentiate between work done on the critical path and work done on non-critical paths. Such methods mask the real situation and mislead the project team because progress on one path often compensate for the delay in other. The paper proposes a more effective method to facilitate …

Computer Programming Tool for the Design of Concrete Mixes for Pavement Quality Concrete Roads in India
Abstract: Basically concrete is a mixture of cement, sand, aggregates and water. These constituents bonds together and hardens with time and give strength to structure. The proportioning of concrete mixes consists of determining relative quantities of materials to be used. Thus to calculate proportions of various components of concrete several mix calculations are required to be performed. Consequently, it is not possible to select at once the exact mix proportion required …
