ABSTRACT  

Background: Light sandwich panels with foam cores are increasingly using  in engineering facilities, And Structural adaptation of these  
elements requires adequate knowledge of their behavior mechanism. Polyurethane PUR is one of the most used materials as filling in the  
locally produced sandwich panels with two covering layers of high- strength steel panels. We do not have scientific references that adopt  
certain specific structural calculation system to adjust the structural design standards by defining its modulus of elasticity on tension,  
compression, shear and adhesion related primarily to the quality and specifications of the product, either direct or long term loading to  
determine the maximum designed load of these panels. Creep phenomenon is one of the most important issues to assess the behavior of  
these elements; the scientific paper contains studying the influence of this phenomenon on the structural designing standards.  
Keywords: sandwich panel, creep, Polyurethane, shear modulus.
