Question

40-mm sides glass polymer fibers composite cube shown in Figure.2. The Glass polymer fibers aligned in the x 
direction. The cube is constrained against deformations in the ? and ? directions and is subjected to a tensile load 
of 60 ?? in the x direction. Estimate the strain, change in length and stresses in ?, ?, and ? directions as well as 
determine the volumetric strain. Illustrate the effect of three-dimensional strain by constructing appropriate 
sketches (before and after deformation for both cube and fibers, assume the fibers have radius of ?). Repeat the 
analysis for lower value of tensile load and higher value in the range of [20 -100 KN] and comment on the overall 
results. What will happen if the force is compression.
