toeasily visualize the components /assemblies in 2D. Now, CAD should be called computer-aideddesign, which becomes an essential tool to aid engineers during engineering design. But inphase II, 3D modeling and drawing associatively in the digital form are only geometries ofcomponents and the assembly. It is obvious that the mechanical behavior of two components,which have same shape, but one is made from steel and another is made from wood, will be quitedifferent. Nowadays, we are in phase III of the CAD, in which the constitutive equations ofmaterial can be assigned to the 3D modeling in the CAD software. When the finite elementanalysis is integrated into the CAD systems such as SolidWorks Simulation, the constitutiveequation of materials

. The goal is to have cases that highlight Coast Guard issues from the fields ofmarine safety, naval engineering, and aviation which are the most common career paths forgraduates in the Mechanical and Naval Architecture and Marine Engineering majors. In addition,material science case studies from outside the Coast Guard will be examined to ensure thatgraduates have an appreciation for national and global material science challenges. Byexamining failures as well as successes, students will have an opportunity to consider theconsequences of poor decision-making and will be able to explore ethical considerations. Ascase studies are incorporated, tools are being developed to assess the impact of this educationalapproach on student learning and

In the 1960’s, some civilengineering college students decided to build a canoe using reinforced concrete. Thishowever was not an innovative idea. In 1848, Joseph Louis Labot of France built the firstconcrete dingy. The first ocean-going concrete ship was an 84-foot long boat constructedin Norway and launched in 1917.

One of the important tasks that the students undertook was checkingthe quality of the aggregates which were used for the construction of the pavement over the spanof the bridge. They conducted elongation index tests, abrasion tests and crushing strength of allthe aggregates that were to be placed in the pavement.For the final construction of the ORR, students observed the working of the mechanized pavingmachines and assisted in estimating the amount of water proofing that was placed on thepavement.

Unfortunately, due to the small size of the fiber core, 1about 9 micrometers, geometric optics does not suffice. Therefore, the modeling of thisphenomenon requires numerical integration of laser optical modes to the fiber optical modes.Figure 1, is a physical schematic of this system.Fortunately, I had discovered a young PhD at an optical research laboratory who had developed acomputer program to calculate the coupling of light in such optical systems.

. It is helpful to the ensuing discussion to draw a distinction between forward and inversecalculations in mechanics. In forward calculations, one is given information such as lineardimensions, material properties, restraints, and applied loads. Analysis is then performed toderive quantities such as deformed geometry, stress, strain, and reaction forces. In a mechanicaldesign, one or more of the derived quantities is specified and an inverse problem is solved, forexample, to optimize a part dimension or calculate a material property requirement. The value ofanalytical engineering is particularly clear in design optimization problems where solutions canbe functionally expressed in terms of the design constraints. CAD models and simulation
