Elastic constants and thermal expansion on UPd2Al3 have been measured. Elastic constants exhibit anomalies around TN = 14.5 K and Tc = 1.8 K. Anomalous behaviors around 0.6 K in C11, C33 and thermal expansion are consistent with previous specific heat measurements. Superconducting Grüneisen constants possess large values of ωa = 23 and Ωc=47.
