Disclosed is a method for obtaining physical properties using indentation impression, comprising: a basic value calculation step of calculating a vertical distance value from an indentation impression; a reference value calculation step of calculating a reference horizontal displacement value that is a horizontal displacement value corresponding to the vertical distance value calculated in the indentation impression from a preset horizontal distance value by using the relationship between the previously obtained vertical distance value and the horizontal displacement value; a mantissa value setting step of setting a mantissa value of an arbitrary physical property; and a checking step of comparing the horizontal displacement value obtained from a preset horizontal distance value with the reference horizontal displacement value using the relationship between the horizontal displacement value according to the horizontal distance value for each physical property, checking whether the horizontal displacement value is within an error range, and checking whether the physical property is a physical property set as the mantissa value, thereby capable of accurately obtaining physical properties of products. 압흔에서 수직거리값을 연산하는 기초값연산단계; 기획득된 수직거리값과 수평변위장값 사이의 관계를 이용하여, 기설정된 수평거리값에서 상기 압흔에서 연산된 수직거리값에 대응되는 수평변위장값인 기준수평변위장값을 연산하는 기준값연산단계; 임의의 물성의 가수값을 설정하는 가수값설정단계; 및 기획득된 물성별 수평거리값에 따른 수평변위장값 사이의 관계를 이용하여 기설정된 수평거리값에서 획득되는 수평변위장값을 상기 기준수평변위장값과 비교하여 오차범위 내인지 확인하여 상기 가수값으로 설정한 물성인지 확인하는 확인단계 를 포함하는 압흔을 이용한 물성 획득방법이 개시된다.
