Elasticiteitsmodulus van gesteenten

Elastische modulus van gesteentespecimens in uniaxiale en triaxiale tests

Automatisch systeem met snelheidsregeling, ook bij het loslaten van de belasting.

Het kan gebruikt worden met een Matest frame met hoge stabiliteit met een capaciteit van 2000 of 3000 kN gekoppeld aan het automatische Servogestuurde systeem Servo-Plus Progress (mod. C104N).

Toepassing: Fysieke eigenschappen

Eigenschap: Granulaten en aggregaten

The appliance includes:

  • Hydraulic system: The combination of a step by step motor and a high-performance valve allows a micrometric action on the pace rate, granting excellent results in the control of the load during both loading and unloading phases. A laser position detector allows a rapid positioning of the piston and a very accurate touch point. This grants a touching sensitivity of test starting of about 0.1 ‰ of the maximum capacity. When used in conjunction with the C104MLPP for the application of the side pressure, the hydraulic system permits to maintain the pre-load level with extremely high accuracy.
  • Electronic measuring system: The digital control unit, controlled by a 32-bit microprocessor, can manage up to 16 high resolution channels (24 bit) for the control of load cells or transducers with strain gages bridge. Data acquired from the system con be used for a further processing.
  • Data acquisition and processing software UTM2 (Universal Testing machine 2) with License for Elastic Modulus on Rocks: This software gives the possibility to use pre-set profiles of the main Standards or modify/create personalized profiles.

The user must enter data concerning the specimen and the kind of test. The appliance manages the average deformation value read by the transducers and processed by the digital unit, than it transmits all tests data throught a serial port RJ45 (Network Connection) to a Personal Computer (not included with the Software). This data will be processed by the software and transformed in load/deformation and load/time graphs, following the specific Standards.

The software gives the possibility to print on a standard printer a test certificate reporting all data and graphs concerning the test and the specimen. The software includes the license “Servonet” mod. C123N. The extensometers (proposed in two versions: A and B) are not included in the supply and must be ordered separately (see accessories).
