At the stage of NPP civil structure design for determination of stress-strain state (SSS) at static and dynamic loading ABAQUS is widely used. Hereto the floor response spectra are determined for calculation of loadings on the equipment at special dynamic impacts (seismic, air shock wave, aircraft crash). In case if the obtained characteristics of SSS or spectral accelerations exceed maximum permissible values, designers take actions on strengthening the corresponding structural components.

Technology of optimization of the NPP civil structures has been applied, developed on the basis of ABAQUS and technologies of IOSO NM.

I have a beginner's question on DCB testing of polymers. The fracture strength during Mode 1 loading increases with crack length due to the compliance of the test specimen. In other words it becomes harder to induce fracture as the crack length increases.Is my understanding correct?

Thanks

Encouraged by its current and prospective customers, Ebatco’s Nano Analysis and Testing Laboratory (NAT Lab) has expanded its nano/micro scale analytical and measurement capabilities significantly. More than ever before, customers can gain insights and comprehension of what is going on and why it has happened at the nano/micro scale.

Dear Colleagues,

New practical case studies made with the aides of IOSO in new engineering fields prove universal capabilities of IOSO Optimization Technology applicable to wide variety of real-life problems. Let us provide you the brief description of the problem that was solved by Italian engineering consultancy company XC Engineering for the well-known Swiss production firm Buhler. The problem was to search for the optimal velocity of the piston in an HPDC process. 

Specific Coatings are used to further increase performance of titanium alloy parts at elevated temperatures. More specifically, Chromium Nitride (CrN) Coatings are designed to perform under conditions of high load and temperature. By using scratch testing it is possible to detect premature adhesive failure of the CrN coating in real-life applications. The test was performed at standard temperature but the test could also be performed at high temperature to better simulate the conditions to which the coating is subjected.
