WebYoung's modulus is a quantity characteristic for a given material. Young's modulus is defined for solids. In the case of liquids, a similar value can be liquid bulk modulus. Young's modulus is most often denoted by uppercase E or uppercase Y. The basic unit of Young's modulus in the SI system is newton per square meter that is equal to one pascal: WebThe modulus of the interlamellar amorphous phase of polypropylene was the highest among all analyzed polymers. At the same time, the modulus of the interlamellar amorphous phase of LDPE and the EOC was significantly lower. In the case of the EOC, the modulus was close to the modulus of the bulk rubbery amorphous phase of polyethylene (≈3 MPa). the plate movements at boundaries are fast
