[ 1 ] - شبیه‌سازی عددی پوشش های ضد اکو حفره دار با استفاده از ترکیب روشهای اجزاء محدود و کانال آکوستیکی

The absorption performance of anechoic coatings depends on the material properties, layer thicknesses and cavity distribution density and cavity size. In this paper a design method based on numerical simulation was presented by combining FEM and acoustic duct method (ADM).  Analyzing of anechoic coatings was performed under active sonar impinging plane wave by normal incident angle. In thi...
