Description

APS (Wille Geotechnik®) has been successfully manufacturing and providing variety range of Shear testing devices for geotechnical applications for many years in different ranges. These products give a lot of flexibilities to the users to run tests with high accuracy and add different upgrading module to system to reach the required testing applications. The temperature control package with the high accuracy and performance makes the possibility to run the tests under different temperature conditions from frozen tests up to high temperature ones. A unique and flexible software along with components bring you different possibilities to use the device and run your test in a better way.


This series of stand-alone electromechanical shear testing devices are designed and manufactured to perform shear tests on soil under different temperature conditions. Many tests require temperature controlling of specimen either for high temperature or for low temperatures and this requires new designed system which would be able to avoid any temperature gradient in sample during tests and make a unique constant temperature condition for the period of testing. The system can be customised in variety test conditions e.g. Static loads with electromechanical motor, different sample sizes either in simple shear or direct shear test format, Low temperature tests or/and high temperature tests which all can be configured together to meet the test requirements.


The temperature controlling system can control the temperature of sample in range of -30°C up to +200°C. The main advantage of device is an accurate testing of soil parameters without tilting and friction between shear box components (e. g. load piston, upper shear box, lower shear box).The normal stress and the shear stress are closed loop controlled by an electromechanical drive system.

The powerful GEOsys software supports all the test procedures with well access to all testing sessions and also gives this feature to manage and run customized test procedures per as any testing needs.

Cyclic Direct-Residual Shear Apparatus

The Cyclic Direct shear apparatus is an automated apparatus with a very high stiffness and includes of two high quality servomotor drives for performing vertical and horizontal shear load (static and dynamic). The electromechanical drive with high resolution and closed loop control rate generates closed-loop strain and stress controlled static axial load and strain and in addition stress-controlled shear forces.


The Vertical load is performed by an actuator connected to the top of the specimen, which is rigidly fixed against horizontal movement and just perform vertical load with high accuracy. It is included of a high-resolution internal displacement transducer to measure the movement of the piston with high accuracy along the height of specimen.The other actuator performs horizontal load to the bottom of the specimen and causes shear strain.


The main advantage of device is an accurate testing of soil parameters without tilting and friction between shear test components. The high quality and low friction double linear guides used to ensure strength and alignment without tilting in normal and shear directions.

Shear Box

The complete shear box system is made of stainless steel and is designed to contain water that surrounds the specimen and allows the specimen to be submerged for saturate conditions. The shear box consists of lower and upper shear boxes with rigid wall either in round or square shape, adaptor loading pad, two porous plates, load piston, sample cutter, dolly and water container for saturated conditions. The Lower part of shear box is locating on a low friction bearing and moves with the small friction just in horizontal direction while the upper shear box is fixed.

The Shear box comes in different sizes e.g. :

• Square:60 x 60 mm ( 36c㎡)
